Silence in the Chapel - The Peregrine Dunn Papers, #1

An urban fantasy/noir set in a Los Angeles transformed by the breaking of an old curse. In this setting, one of the people responsible for breaking the curse--Peregrine Dunn--acts as an informal private investigator, helping out folks whom the authorities might have forgotten... or who don't want the authorities to know. In Silence in the  Chapel, Peri is approached by an ancient order of Templar Knights, hoping to find out why one of their allies tried to commit suicide.
Things, as one might guess, aren't as simple as presented.
