Practised, popular entertainment, in a novel of murder, as Ellery Queen returns to Calamity Town to help Davy Fox, Pacific war ace and now a psychoneurotic casualty, obsessed by the long ago conviction of his father as the murderer of his mother -- and sure that he will follow in his father's footsteps and murder his young wife, Linny. To rid Davy of his obsession, Ellery re-opens the old case, re-examines evidence which once had seemed to make Davy's father the only possible suspect, revives the hope of another culprit, and with some pretty lightning longshots, clears Davy's father and dismisses the case as suicide. Somewhat out of the Ellery Queen groove -- but interesting.
