They walked into a gallery that displayed Roman antiquities. The professor pushed aside a corner shelf to reveal a hidden door whose glass paneling had been smashed and steel grate bent back. He fumbled in his pocket for a candle and a cigarette lighter. They descended the narrow set of stairs to metal doors that were wide-open, with no sign of forced entry. A wall sealed the space beyond the door. The concrete bricks had been pried away to make a large opening.

They climbed through the opening into a hot and airless room. An acrid stench assaulted their nostrils. Footprints on the dusty floor had been cordoned off with yellow tape placed at the crime scene by a team of investigators.

Carina glanced around. “Where are we?”

“The basement storage area. There are five rooms down here. Few people in the museum even know this place exists. That’s why we thought the collection was safe. We were wrong, as you can see.”

He moved the candle in an arc. Its yellow light fell upon dozens of plastic fishing boxes thrown willy-nilly around the room.

“I’ve never seen such absolute chaos,” Carina whispered.

“The boxes held cylinder seals, beads, coins, glass bottles, amulets, and jewelry. Thousands of items are missing.” He brought the candle over to dozens of larger plastic boxes that lined the walls. “They didn’t bother with these. Apparently, they knew they were empty.”

Corporal O’Leary surveyed the wreckage with a street fighter’s eye for entrances and exits. “If you don’t mind my asking sir, how’d they know how to find this place?”

Nasir’s heavy features drooped and he gave a glum nod of his head. “You Americans aren’t the only ones who have reason to be embarrassed. We suspect someone on our staff with intimate knowledge of the museum alerted the thieves to this room. We have fingerprinted our staff, except for the head of security, who has not come back to reclaim his job.”

“I was wondering why I didn’t see any evidence of the door being forced,” Carina said.

“The thieves came into the basement the same way we did, but they had forgotten torches or never expected they would need them.” He picked up a piece of burned rubber foam. “They used this material from upstairs for torchlight. The stuff burns quickly and the fumes would have been terrible. We found a set of keys on the floor. They probably dropped the keys and couldn’t find them. They missed thirty cabinets with our best cylinder seals and tens of thousands of gold and silver coins. I’d guess about ten thousand excavated artifacts are missing. Hundreds of boxes were left intact, praise Allah.”
