Lost Dog — Alan Russell

Detective Michael Gideon is used to being handed L.A.'s oddest cases, but his newest one assigned itself. When Gideon's K-9 partner, Sirius, rescues a lost dog from a pack of coyotes, the duo tries to return her home -- only to discover her owner is missing.

Heather Moreland has clearly disappeared under suspicious circumstances, and the more Gideon digs into her past, the more he's convinced of her abduction.

As Gideon strives to help the missing woman, he is also troubled by the suspicious death of Detective Langston Walker, the leader of a support group for families of murder victims. The last time they'd met, Walker told Gideon about a cold case he had reopened, making Gideon wonder if the detective's demise is the accident everyone believes.

In this third book in Alan Russell's gripping cop-K-9 series, Gideon and Sirius race to save a young woman -- and stop another killer from striking again.
