David Silver Series by Lynn Hightower

Life's tough for Detective David Silver. His marriage is crumbling, a serial killer's on the loose, and his new partner looks like a seven-foot stingray and smells like fresh limes. But when a murder case leads to a frightening conspiracy, Silver needs all the help he can get--even from an alien.

The electrifying new novel by the author of Alien Blues. When pouchlings of the stingray-shaped, lime-scented Elaki are found murdered in their beds, Detective David Silver immediately fixes his attention on Angel Eyes, who claims to have been a victim of persecution on her homeworld, and who's achieved almost saintly status in the eyes of both human and Elaki.

Detective David Silver and his Elaki partner, String, are in the line of fire when an arsonist goes on a rampage. Killing both humans and Elaki, the madman wipes away all clues by torching the crime scenes. Even more disturbing, the burned-out real estate is being snatched up by members of a bizarre cult.
