Murder in Four Parts

When Sheriff Dan Rhodes is asked to join the Clearview Barbershop Chorus, he suspects that there's an ulterior motive, mainly because he can't sing a note. He's momentarily distracted by a rogue alligator on the loose, but shortly afterward, Lloyd Berry, the director of the chorus, is murdered. Berry is suspected of embezzling money, and he's leaked the information that a member of the chorus ordered a singing valentine for a woman who isn't his wife. Later, Rhodes discovers that Berry has been gambling on eight-liners at Rollin' Sevens, a barely legal operation in a strip center on the outskirts of town.
Rhodes also must deal with the usual assortment of small-town crimes: a man dressed in his underpants and cowboy boots picketing a law office, dogfood theft, and attempts on the life of a man who likes to root through garbage. Rhodes sorts through clues that involve geocaching and barbershop singing with the help of a few oddball local characters before he solves the crime.
