Ax

Eighty-six-year-old George Lasser was the superintendent of a building in the 87th Precinct until just recently. Unfortunately his tenure ended in the building's basement with a sharp, heavy blade of an ax in his head...There are no witnesses, no suspects, and no clues. The wife and son? They're both a little off-kilter, but they have alibis. Just when Carella and Hawes are about to put the case on the shelf, the killer strikes again. Now the detectives are hot on the trail of a man crazy enough to murder with an ax.One of the 87th Precinct series' finest installments, Ax is a sharp, intense crime thriller that is classic Ed McBain. The New York Times hails it as "the best of today's police stories--lively, inventive, convincing, suspenseful, and wholly satisfactory."
