An Accidental Corpse by Helen A. Harrison

They are on vacation, but after witnessing an accident, they find themselves drawn into the case.

Dunemere Books and Edelweiss allowed me to read this book for review (thank you).  It has been published and you can buy a copy now.

It's an awful car crash that kills the driver, one of his passengers and injures the other badly.  The only problem is that the dead passenger was already dead.  Someone had strangled her to death.  There's no end to who might have killed her.  Most of the men in the community knew her.  The only clue that might help is that she scratched the killer.  They don't find any scratches on those they question.

The dead artist had a lot of enemies to check out but none had scratches.  I didn't figure out who the killer was until they revealed it.

I didn't feel much sympathy for the artist but I did for the silly women so infatuated with him.  I'm glad they finally found the killer.
