Blurb: "The axe had been wedged into the janitor's skull, splitting it wide open... that's how Steve Carella's most complex case began.
The 'leads' lead in all directions: a too-obvious Negro suspect; a small-time crap-game; a pre-war tax swindle; the janitor's mad wife and strange son, both expensively cared for...
When the next victim is an 87th Precinct man, a slow-burning case flares into a red-hot outrage and every available cop sets out on a personal manhunt for the killer."
