Anthony Boucher quotes:

Richard Stark writes a harsh and frightening story of criminal warfare and vengeance with economy, understatement and a deadly amoral objectivity-a remarkable addition to the list of the shockers that the French call roman noirs.

Eliminate the impossible. Then if nothing remains, some part of the 'impossible' was possible.

Critical sobriety is out of the question so long as this master of terror-in-the-commonplace exerts his spell.
