Cal Wirther is guilty. His prosecutors are certain. He programmed nanites to form networks in women’s brains, influence their decisions and turn them into unsuspecting call girls.

Unfortunately for Assistant District Attorney’s Marcia Fong and Peter Goode, this may be a case where technology outpaces the law. Their only physical evidence is millions of nanites found in the women’s heads. They review folders of potential witness.

Each witness adds to their case from the secretary, who was there from the beginning, to a graduate student student who cracked the case. Each witness also presents difficulties. Nanites tampered with the victim’s memories. A collaborator’s plea deal excludes crucial details, and their best witness, the forensic epidemiology graduate student who cracked the case, suffers from post traumatic stress disorder.

Follow along with the prosecutors to examine pieces of the puzzle and see if they can present a complete picture.
