It's the summer of 1933, and Oxford don Clive Staples Lewis, better
known to his friends as Jack, is on a walking holiday with his brother
Warnie and young friend Tom Morris. When Jack's wallet is accidentally
destroyed, they visit a bank to replenish their funds - and walk
straight into the scene of an impossible murder.The victim is in the
vault of the bank alone, cut off by brick and steel from the rest of the
world. Yet he has been stabbed from behind and the murder weapon has
vanished. A 'locked room' mystery - which would have baffled the
cleverest sleuths of the Golden Age of detective stories - is tackled by
the brilliant mind and larger-than-life personality of 'Jack' Lewis,
beloved creator of Narnia and formidable defender of the Christian
faith.
