A story of two brothers, both writers of crime novels, one a fine, upstanding gentleman and the other a moody, neurotic, psychopath. The other is determined to create a 'faked' version of a perfect crime he intends to commit when an ex-convict visits them. They are both in love with their shared-stenographer-secretary.
