The 'Hangover House' of the title is the scene of a fatal stabbing early in the story. It has taken place during a party in which most of the suspects attended.
In the fashion of thrillers of this era (1950's) there are gay young things (gay in the old sense of the word),mysterious foreigners and not a few cads and rotters hanging about. The official police are helped,or hindered dependent on your point of view by Storm Kennedy,a private detective on the spot at the time of the murder.
Taken in the right way as pure light entertainment,this is a fun read. ( )
