Chapter 2: The Puppeteer in the Shadows

After leaving the museum, Otto dialed Marlene Vogt’s number from a spot near Bismarck Square. Ten minutes later, Marlene got out of her car. She first examined his hands, then the evidence bag.

"The key had just fallen out from beneath the stone disk’s base," Otto said in a low voice. "The eagle emblem is heavily worn, but the teeth look like they were re-machined recently."

Marlene put on her gloves to observe. "Since you touched it, its value as scene evidence is discounted, but the machining marks can still be handed to the lab for analysis."

The two returned to the exhibition hall. Security logs showed that the door to the underground archive room had been opened seventeen minutes prior.

The archive room bore no signs of forced entry; the access control system recorded only Otto’s authorization. However, the rolling cabinet at the far end was off its track, with fresh fingerprints left in the dust.

"Someone cloned your access credentials, or they’ve altered the logs," Marlene said. "I need to interview every overnight guard individually."

The drawer storing the stone disk’s excavation materials was still locked, but its numbered label was affixed upside down.

"The archivist would never label it that way," Otto said. "The drawer was taken out. Whoever put it back is unfamiliar with the museum’s rules."

All of the 2003 excavation photographs were there; only the packaging inventory list from before the disk’s accession was missing.

"What does the list prove, aside from the crate dimensions, seal numbers, and handling chain?" Marlene asked.

"It also proves whether the disk was metal-detected during accession, and who first noticed the anomaly," Otto replied.

Marlene secured the archive room, ordered the records and fingerprints be collected, and had Otto recount the discovery. Otto described the anonymous letter, the carved symbol coordinates, and the 1974 blueprint, but withheld his promise to accompany Anna to see Schwartz.

Marlene said: "If you want to clear your name, stop filtering facts for anyone. Omissions will strip the truth of its weight."

"Anna only assisted with the symbol comparison. She suggested I call the police. She never touched the key, and she didn’t enter the archive."

"I’ll judge for myself whether she’s uninvolved. You just ensure you stop conducting solo investigations."

"There’s a conference on the disk’s dating tomorrow morning. Weber will publicly present the 3D scans; I have to be there."

At that very moment, Friedrich Weber was calibrating the projector in an empty university lecture hall. The stone disk model hovered on the screen, the carved symbols magnified layer by layer. His paper was already formatted; its conclusion classified the disk as a purely Neolithic relic, based on evidence from mineral deposits, wear direction, and scan density.

To Anna, who was verifying images in the back row, Weber said: "Move Otto’s embedded-metal hypothesis to the appendix. His evidence is insufficient, yet it warrants a clear rebuttal."

Anna closed her laptop. "If you only display the cross-sections that support your conclusion, the audience will assume the scan revealed no anomalies."

"Anomalies don’t equal later modification. Fissures, moisture differences, and restoration adhesives can all produce similar echoes."

"Then show the raw data and let the colleagues decide. Otherwise, your technical authority just becomes a prettier smokescreen."

Weber knew every scanning parameter, and he also knew that no one could replace Otto’s understanding of the symbols, which made him even more unwilling to let unverified speculation steal the paper’s priority. Pointing to the center of the disk, he said: "I will release the complete model, but I won’t let Otto erase two years of measurement work with a single claim about war-era embedding."

"Otto is questioning the disk’s history, not denying its primary dating. You’re tying two separate things together."

"Academic history remembers who gives the first complete explanation; it doesn’t save a seat for the cautious."

"If a 'complete' explanation is achieved by deleting the blanks, the earlier it’s published, the more embarrassing the correction will be."

That morning, Anna waited for Otto in front of the archive hall and saw Marlene behind him.

"You went back to the museum last night, didn’t you? What happened in the archive room? Was the key taken?"

Otto said: "The inventory list is missing, and the access logs were impersonated. Marlene believes someone knew in advance that the key was hidden in the base."

Marlene asked Anna: "Where were you last night? What equipment did you use? Did you send the coordinates to a third party?"

"I stayed in the university lecture hall assisting Weber. The coordinates are only in my offline notes. I can give you my phone to check."

Marlene stopped them at the entrance: "Schwartz hasn’t arrived yet, and the archive has been secured. Any consultation must leave a complete record."

Ernst Schwartz arrived twenty minutes late. Seeing the police car, his step faltered. Marlene showed her credentials and handed him an electronic copy of the 1974 blueprint.

Schwartz glanced at it once: "The signature looks like mine, but back then I was just an apprentice. I couldn’t have been responsible for this survey, nor did I have the authority to sign it."

Otto stared at the hand holding his umbrella. "You’re denying the authority, not the handwriting. How did this blueprint enter the collection? And why does it mark the stone disk’s coordinates?"

"Old archives are moved frequently. Misfiling, backdating, and copying are all common. You can’t fabricate a secret discovery based on that."

Anna said: "The paper watermarks, ink, and binding holes can all be tested. If you think it was misfiled, you should be the one advocating to examine the original volume."

Schwartz’s expression hardened: "The original volume is part of a restricted donation. Without an authorization letter, no one can touch it today."

Marlene requested that the case files be preserved and borrowing be frozen. As Schwartz signed, Otto noticed his final stroke habitually hooked to the left, perfectly matching his old signatures.

Marlene murmured: "Seeing a contradiction isn’t the same as having evidence. Push too hard, and he’ll just hide behind the procedures."

"He’s not afraid of the blueprint’s authenticity; he’s afraid that it somehow knew the disk’s location in advance."

Schwartz suddenly looked up: "Mr. Wolff, some old records lack context. Isolating them for interpretation only harms those who are still alive."

“Then give me the background. Who saw the stone disk in 1974? Who buried it again in the mountains?”

“I can only tell you this: it involves a private safe-deposit box. Its owner is dead.”

With the meeting approaching, Schwartz fell silent. Marlene stayed behind to handle the archival-protection procedures, while Otto and Anna headed for the university. On the way, Anna handed Otto Weber’s paper abstract.

Otto skimmed the conclusion. “He treats the continuity of the surface deposits as proof that the whole thing was never opened. That’s a leap too far.”

“There’s a ring of weak echoes in the original slices. Weber explains it as a natural fissure, but I think the shape is too regular.”

Otto enlarged the image. “Regularity isn’t the key. The light source is fixed in every image. The weak echoes may have been swallowed by the rendered shadows.”

“Are you planning to challenge him in front of everyone, or ask to see the unrendered volumetric data first?”

“Let him give his full presentation. If he shows the model himself, I’ll only point out what the model can actually prove.”

The lecture hall was packed with experts in archaeology, geology, and conservation. Weber displayed mineral thin sections, sediment layers, and abrasion simulations, then rotated the stone disk’s three-dimensional model.

“Multiple lines of evidence support the same conclusion: the body of the stone disk, the engraved symbols, and the sealed deposits all belong to the same early period.”

Someone asked about the metal reaction. Weber switched to a cross-section. “What appear to be later metal components are merely a misreading caused by localized high-density minerals and old repair material.”

Otto kept his eyes fixed on the projector. When the model turned to the back, a curved dark band appeared along the disk’s edge, then vanished beneath the automatic fill light.

Weber began his summary. Otto raised his hand. “Please return to that rear angle. Turn off the automatic fill light, then shift the virtual light source fifteen degrees to the right.”

Weber frowned. “This isn’t the original scan, merely a surface rendering. Changing the light source can’t replace internal measurements.”

“Precisely because it’s only a rendering, I’m not discussing the material. I’m asking why the model needs fill light to conceal a fixed shadow.”

Weber did as instructed. The light shifted, revealing an incomplete ring of elliptical shadow in the center of the stone disk, its edges far too smooth for a natural fissure. A murmur swept through the hall.

Otto pointed to the ellipse’s lower edge. “The original projection angle flattened the depression into a difference in surface color.”

Weber brought up the mesh. “That only shows a slight collapse in the reconstructed surface. It doesn’t prove the existence of an artificial structure inside.”

“Not from a single frame. But as the model rotates, the shadow boundary remains closed, while its depth doesn’t change continuously with the surface curvature.”

Anna stepped backward through the model frame by frame. The elliptical shadow appeared again and again, like a flattened bubble inside the stone disk.

“Natural fissures expand along the grains,” Otto said. “This edge crosses three separate textures. That means there’s at least an independent cavity inside.”

Experts in the front rows began demanding to see the unprocessed slices. Weber’s face went pale. He closed the paper’s conclusion page and opened the raw volumetric images. Amid the gray noise, the elliptical outline was even clearer, with a slender region of high-density reaction at its center.

Weber’s voice was low. “I admit the cavity exists. But its date is unknown. Nor can we declare, on that basis, that someone embedded metal during the Second World War.”

“I made no declaration about its date. I’m only asking that later intervention be listed as a testable hypothesis, and that we suspend the conclusion that the disk was never opened.”

Weber stared at the data. “The paper will be delayed. The stone disk will be rescanned. Until the results are in, no one publishes an explanation of the cavity ahead of the others.”

“We can co-author a preliminary report and place the raw data in synchronized evidence storage. No one gets to seize the conclusion by beating the others to publication.”

Weber extended his hand. “I accept. But if the metal is from the same period as the body, you must publicly withdraw your wartime hypothesis.”

Otto shook his hand. “If the evidence says so, I’ll withdraw it myself—and state clearly where I was wrong.”

Questions flooded the hall. Otto stepped outside before realizing that his palm was drenched in cold sweat. Anna handed him a glass of water. “If you’d reached your conclusion half a minute earlier, Weber could have shut you down with the natural-fissure argument.”

“I only saw an anomaly. Proving the cavity will require new tomography and material analysis.”

“At least no one can call your suspicion mere stubbornness anymore. The price is one additional co-author.”

Otto looked out the window. “The greater price is that the person in the shadows now knows we’ve discovered something else inside the stone disk.”

His phone vibrated. Marlene sent a notification: the electronic backup of the missing-items list had also been deleted. The operation took place just before the meeting began.

They hurried back to the archive. There were no signs of a break-in, yet the backup had been deleted using the director’s credentials. Schwartz admitted the account belonged to him, denied carrying out the operation himself, and refused to explain the private safe-deposit box.

“Your account, the drawings, and the missing-items list all point to you,” Marlene said. “Silence won’t protect the archive. It will only let someone else decide the truth for you.”

Schwartz leaned against the door, his voice old and weary. “The box was transferred after its owner died. I don’t know who keeps it now. I only know it must not be opened.”

Otto pressed him. “Does it contain the record of the stone disk’s first discovery—or evidence left behind by the person who buried it again?”

Schwartz closed his eyes. “I saw the box once, when I was young. There was no stone disk inside. Only a list of the dead and half of an inscribed stone.”

Marlene was about to continue questioning him when her phone suddenly lit up. The number was concealed, impossible to call back. She looked at Otto, then at the closed director’s office, and turned the screen toward them all.

The text contained only one line:

“The stone disk isn’t yours. Find the dead man’s box.”
