The Best That Ever Did It. By Ed .Lacy. (HutchinSon,
10s. 6d.) Two apparently purpose- less and apparently unrelated killings on the side- walks of New York lead to unfolding of ingenious crime that had led only inadvertently to murder.

Neat, brisk and exciting-the only puzzle still unsolved at the end is what on earth the title means.
