He's the Guy! - Suzi B. Mystery #4
A man calls the police to report that he saw what he believes to be some gun flashes in the window of an apartment near his boat.
When the police respond to the call they discover two dead men who look like they shot each other, and the CSI and medical examiner agree that it was a shoot-out... but Suzi thinks there's more to this incident than meets the eye - and sets out to prove it.
