City of Saviours by Rachel Howzell Hall
Seventy-three-year-old Eugene Washington appears to have died in an unremarkable way, but LAPD homicide detective Elouise "Lou" Norton is positive that something isn't right. Especially when she learns that the only family Washington had was his fellow church-goers. Could the murderer be sitting in one of those red velvet pews? And is someone protecting the wolf in the flock? Lou must force the truth into the light before it's too late.
