Great debut murder mystery 2021. John McMahon is already being listed with the best.

A complicated and fascinating plot.

P.T. Marsh was a good detective.

Then his wife and son were killed in an accident.

Months later he’s not so good — drinking, blacking out.

Late one night he agrees to help out a woman by confronting her abusive boyfriend.

When the next morning he gets called to the scene of his newest murder case, he is stunned to arrive at the house of the very man he beat up the night before.

He could swear the guy was alive when he left, but can he be sure?

What’s certain is that his fingerprints are all over the crime scene.
