The Cat Who Turned On and Off — Lilian Jackson Braun

The team of Koko, the brilliant Siamese cat, and Qwilleran, the reporter with the perceptive moustache, is back in action--with an adorable female Siamese, Yum Yum, added to the household.

When Qwilleran decides to do a feature series on Junktown, he gets more than he bargained for. Not the dope den he anticipated, Junktown is a haven for antique dealers and collectors--as strange a lot as the crafty reporter has ever encountered. When a mysterious fall ends the career--and the life--of one of Junktown's leading citizens, Qwilleran is convinced it was no accident. But, as usual, it takes Koko to prove he's right.

Qwilleran--a prizewinning reporter with a nose for crime. Koko--a Siamese cat with a tiair for mystery. Yum Yum--a lovable Siamese adored by her two male companions. The most unlikely, most unusual, most delightful team in detective fiction!
