Newspaperman Jim Qwilleran and his brilliant Siamese cat, Koko, are back in action - with a lovable female Siamese named Yum-Yum added to the household.



When Qwilleran decides to do a newspaper feature about Junktown, he thinks he'll be writing a heartbreaking story about a dangerous, run-down neighborhood. To his surprise, however, Junktown turns out to be a haven for Moose County's eccentric antique dealers and collectors.



Qwill is almost ready to give up on his story when one of Junktown's leading citizens is killed in a mysterious "accident." Before he knows it, Qwill finds himself embroiled in a mystery in which antique English bookcases aren't the only things the dealers are shellacking. As usual, however, only Koko's assistance will lead Qwill to the truth.
