Doppelganger Gambit

It looks like straightforward suicide to Detective Janna Brill. Starship outfitter Andy Kellener locked himself in his office after hours and took a fatal drug dose. But Brill’s exasperating new partner Mama Maxwell thinks it’s murder, and his chief suspect is Kellener’s partner Jorge Hazlett. The trouble is, Hazlett has an airtight alibi. In 2091's cashless society, every purchase is made with a data chip implanted in the individual’s wrist...and Hazlett’s bank records put him in a shopping mall clear across town at the time of his partner’s death. To get their man, Brill and Maxwell have to prove Hazlett faked his shopping spree...and possibly destroy law enforcement’s best tool since DNA for tracking suspects!

Reviews
“This is a grittily realistic police procedural set in the 21st century. Don’t miss this one.” Analog Magazine

“Like many procedurals the novel’s strength rests as much on the personalities of the cops as in the solving of the crime, and Brill and Maxwell make an entertaining pair.” Locus Magazine

“Police Procedural SF is rare — that makes Ms. Killough’s fun romp all the more appreciated. The characters, plot, indeed the whole future society are very well developed in this novel.” SF Review 34
