Skullduggery — Caryl McAdoo

A friend loveth at all times, but a brother is for adversity.There's a human skull with a hatchet still in it in a crumbling shack in the river bottoms. Four friends set out to discover who it belonged to and who left the hatchet behind, and they're going to write a book about it! Morgan and Charity Lowell are back, and she's arranged for her handsome husband to solve the mystery and write another book about it--this time with the famous dime novelist May Meriwether. It's hard not to get in the big middle of the investigation though!
