A Cat Under the Mistletoe — Lydia Adamson

Alice Nestleton--actress, cat sitter, and amateur sleuth--is ringing in the holidays with a new client: a lovely tortoiseshell cat named Roberta. But sometimes this fickle feline turns into the kitty from hell, which is where Manhattan animal therapist Dr. Wilma Tedescu enters the picture. Make that exits. On Roberta's very first appointment, Alice finds the good doctor as dead as a Christmas goose, proving that cat "shrinks," unlike cats, are decidedly short of nine lives.

Suspicion falls on the doctor's estranged husband...and then on Alice. As Alice sets out to find the real killer, the fur really flies. It isn't long before her nose for clues lands her a whisker away from a killer who doesn't pussyfoot around with murder....
