UFOs in Mooseville? Rumors abound that a missing backpacker has been abducted, and it looks like Jim Qwilleran's sedate summer may be interrupted by an investigation -- with the help of his own little aliens, Koko and Yum Yum. And when the backpacker's body turns up -- and transplanted Floridian Owen Bowen is found dead soon afterward -- the search for intelligent life turns into a close encounter with a killer.

Meet prizewinning reporter Jim Qwilleran and his extraordinary Siamese cats Koko and Yum Yum -- the most unlikely, most unusual, most delightful team in detective fiction!
