The unspeakably wealthy (and generally unspeakable) Jonathan Royal has decided to throw a party and, just for fun, has studded the guest-list with people who loathe one another. When a blizzard imprisons them all in Royal's country house, murder ensues. In true Christie-esque tradition, there are nearly as many suspects as there are potential victims. Eventually, Inspector Alleyn makes his way through the snow to put things right.
