[In They Never Came Home the] doubts about Larry's character are skilfully developed, so that it comes as little surprise to the reader to find that he had arranged to disappear, taking advantage of an accident that left Dan an amnesia victim. Save for that contrivance, the plot is deft; the story has action and suspense, and a compelling dénouement. (p. 157)
