The Cat Who Went Underground (The Cat Who... Series #9)

Jim Qwilleran packs up his old kit bag and his two Siamese cats, Koko and Yum Yum, for a sun-and-fun summer at his log cabin in Moose County. Their vacation starts out ominously with the disappearance of a handyman hired to patch up Qwilleran's cabin. But the felines really start throwing catfits when they come across a dead body or two...A serial killer may be right under Koko's nose, and now this ingenious Siamese must dig deeper to clear poor Qwilleran of suspicion--and dig up the motive for a catastrophic crime.
