The Gray Ghost Murders by Keith McCafferty

Montana’s favorite fly fisherman detective is back on the case in the second installment of the Sean Stranahan Mystery Series. When the graves of two men are discovered on Sphinx Mountain, Sheriff Martha Ettinger suspects murder. But with the only evidence a hole in a skull that might or might not have been caused by a bullet, she once more finds herself turning to private investigator Sean Stranahan for help. Stranahan already has a case, having been hired by a group of eccentric fly fishermen called The Madison River Liars and Fly Tiers Club to find a valuable fly that they suspect has been stolen. Could the disappearance of a vintage Gray Ghost from a riverside cabin in the Madison Valley be connected to the gray ghosts who haunt Sphinx Mountain? Stranahan will cross paths, and arms, with some of the most powerful people in the valley to find out, in a novel that is sure to capture new fans for one of the mystery genre’s rising stars.
