Put on your deerstalker hats and get out your magnifying glasses, because this Adventure Time collection is a real whodunnit!

Between stuff going missing all around Ooo (surely this sentient cube Finn and Jake found has nothing to do with it . . . ?) and pranks ruining Masquerade Day (eggs are for eating, not for throwing!), our heroes are going to need to put on their thinking caps to solve this duo of crazy conundrums! Luckily, Finn, Jake, and BMO are . . . on the case! (Sigh.)

This detective-worthy compact edition collects Graybles Schmaybles written by Danielle Corsetto (Girls with Slingshots, The New Adventures of Bat Boy) and drawn by Bridget Underwood, and Masked Mayhem written by Kate Leth (Mall Goth, Patsy Walker, A.K.A. Hellcat!) and drawn by Bridget Underwood—as well as shorts by Meredith McClaren (Meat Eaters, Black Cloak)!
