Lilian Jackson Braun 2-in-1 Edition, Volume 2: The Cat Who Said Cheese / The Cat Who Tailed a Thief

Another pair of Lilian Jackson Braun's best mysteries—featuring Jim Qwilleran and his lovable Siamese cats, Koko and Yum Yum—are presented here in this 2-in-1 edition:
The Cat Who Said Cheese: The events at the Great Food Explo in Moose County are overshadowed by the arrival of a distracting and mysterious woman, and Qwill and his Siamese sidekicks investigate a fatal explosion at the New Pickax Hotel.

The Cat Who Tailed a Thief: Trouble arises when a local banker dies under suspicious circumstances, leaving behind a flashy young widow, an unfinished house-restoration project, and a trail of clues as elusive as a cat burglar in the night. It's up to a trio of sleuths--prizewinning reporter Jim Qwilleran and the resourceful Koko and Yum Yum—to solve the mystery.
