An investigator must solve a seemingly impossible theft in this comedic sci-fi mystery by New York Times–bestselling author Alan Dean Foster .

The room—surrounded by cameras, motion sensors, and alarms, and guarded by rotating security crews twenty-four seven—was supposed to be impenetrable. No one should have been able to approach the vault unseen.

So how did the irreplaceable pharmaceuticals stored there get stolen? How did someone breach the vault three times and escape unnoticed and without leaving a trace? It's a mystery that falls to insurance adjuster Roderick Manz to solve. Assisted by a humanoid robot, an AI, and an off-world partner named Vyra with secrets of her own, Manz is on the hunt for the most clever thieves he has ever encountered.
