Scooby-Doo Team-Up #21

Description

It's hard enough for Scooby and the gang to crack the mystery of a Dickensian Yuletide ghost, but it's harder with 'help' from Mystery, Inc.'s newest member: Harley Quinn! Harley's decided to try a new career as a ghost-busting detective, and when she swings that giant mallet, nobody's going to tell her 'no.' But the gang doesn't suspect the real reason for Harley's relocation: She's on the run after a 'lover's spat' with The Joker, and Mistah J wants her back!
