Maybe some will enjoy a little humorous fiction about Melvin Cogsworth - 'Metal Detector Detective'.
He's a cross between Sam Spade/Mel Fisher/Ace Ventura. Short chapters, well written will keep you interested.
I particularly enjoyed, and found humorous enough to chuckle, The Problem of the Tiger-Striped Cat.
You should read in sequence however.
