The Black Cat Sees His Shadow - Kay Finch - Bog

Mystery novelist Sabrina Tate and her cat, Hitchcock, set out to catch a conniving killer in the next Bad Luck Cat mystery from the author of The Black Cat Knocks on Wood and Black Cat Crossing...
The town of Lavender, Texas is buzzing with tourists, and local businesses are pulling out all the stops for the annual Pumpkin Days Festival. On the eve of opening day, Sabrina comes face-to-face with her doppelgänger, Tia Hartwell, a caricature artist at the festival. The similarities between the two women are striking, including their matching black cats. 
Sabrina learns that her new twin Tia has an enemy: bad-tempered jewelry vendor Calvin Fisher. When Fisher is found slumped over dead in his pickup, Tia tops the suspect list. With the help of her feline sidekick, Sabrina must clear her new look-alike friend before she finds herself in a deadly case of double jeopardy.
