Murder, My Tweet: A Chet Gecko Mystery (Chet Gecko, 10)

Right in the middle of a run-of-the-mill case, the powers that be finger Chet's fine-feathered partner, Natalie Attired, as a no-goodnik blackmailer and boot her out of Emerson Hicky quicker than you can say, “Boot her out of Emerson Hicky.”

Chet, of course, tackles the case for free. Mess with his partner, mess with—well, somebody. (Natalie's the brains of the outfit.) But just when Chet thinks he might clear her name, Natalie disappears, leaving behind a reddish smear that looks kind of like cherry ladybug jam. . . . Is it murder, or something serious?
