Collateral Casualties - Kassandra Lamb

A dark secret triggers a deadly game of cat-and-mouse...
When a former client reaches out to psychotherapist Kate Huntington and reveals a foreign diplomat's secret past, then dies of "natural causes" just days later, Kate isn't sure what to think. Was the man delusional or is she now privy to dangerous information?

Soon she discovers her client was totally sane... and he was murdered. Now someone is trying to eliminate her, plus anyone and everyone she might have told. As the cat-and-mouse game escalates, Kate and her husband, along with their friends and several operatives of his P.I. agency, struggle to stay one step ahead of a ruthless assassin who's bent on protecting the ambassador's secret.
