A Case of Volatile Deeds, by W. S. Gager
Mitch finally scores a weekend dinner with a cute receptionist, but true to his reporter instincts, an explosion in a high rise office building makes him stand up his date as he runs for an exclusive. Mitch learns that much of what he knows about his date and her work aren’t what they seem.
His world continues to twist when the police captain asks for his help and a city hall informant is found floating in the river. Mitch must keep his head down or a cute dog with a knack for finding dead bodies will be sniffing out his corpse.
