The Cat Came Back by Louise Clark

Stormy the Cat, rescued by journalist Quinn Armstrong, is not what he seems.

Young mother Christy Jamieson just learned her husband, Frank, embezzled his trust fund, sold their Vancouver mansion, and ran off with a socialite. Worse, Frank's trustees are telling Christy to let them handle it. But they aren't doing anything, and Frank's enemies are coming after her and her daughter.

Desperate to find Frank and fend off his enemies, Christy asks Quinn for help. His price: the dirt on Frank. But the closer Christy and Quinn get to the dangerous truth, the more convinced they become that only the one who knows where Frank is at, is Stormy the Cat.
