Shadows on the Stairs

For anyone who watches the Basil Rathbone/Nigel Bruce "Sherlock Holmes" series of films, you will recognise almost all of the cast from this afternoon feature about guests in a boarding house who find themselves amidst a set of curious murders. It's all run-of the mill stuff but a decent enough adaptation of Frank Vosper's (himself, quite an interesting figure) play "Murder on the Second Floor".
