A dozen shock treatments for varying degrees of murder and attempted murder attest to the capabilities of this author. He produces a cool chill and a calculated thrill. The title story cliff- hangs on an old lady locked in a vault -- will help come in time? Portrait of a Merderer again depends on a vault and ties in with Witness for the Prosecution, Little Boy Lost and A Boy's Will for dominating, demon children; Love Comes to Miss Lucy has been tapped for collections. With other death-dealing, successful and backfiring, this lingers, lethally.
