Roderick Alleyn No. 11.  A host, with a wry sense of humour, assembled a party including seven people with very good reasons for killing each other, in a snowbound English country house.  The victim was one of the seven – but had he been mistaken for someone else?  The suspects all had alibis, for no-one could’ve committed the murder without passing the dancing footman – and no-one had passed him. By the time Alleyn arrived, it was apparent that the crime could not have happened… Cover art by Philip Hood.
