 Audible Original Fiction by Drew Hayes

This book was the sequel to The Case of the Damaged Detective, and it was similar to that story.

At the beginning of the story, Sherman Holmes and his assistant Joel Watson have set up shop, calling their firm "The World's Greatest Detective Agency,"  and ensuring (it seems) that only weirdos and kooks would consult them. Or, it turns out, desperate people... A young woman called Lauren comes in with a case no one else wants to take: she works for a ghost tour that might really be haunted?

Sherman will solve the case of course, and there will be plenty of laughs along the way. This was another fun story.
