Eldritch Swan is a dead man. Or at least that is what his nephew Stephen has always been told. Until one day Eldritch walks back into his life after 36 years in an Irish prison. He won't reveal any of the details of his incarceration, insisting only that he is innocent of any crime. His return should be of interest to no-one. But the visit of a solicitor with a mysterious request will take Eldritch and his sceptical nephew fromsleepy seaside Paignton to London, where an exhibition of Picasso paintings from the prestigious Brownlow collection proves to be the starting point on a journey that will transport them back to the Second World War and the mystery behind Eldritch's imprisonment.

The subsequent disappearance of those paintings began a trail of murder and intrigue which was to have a catastrophic effect on Eldritch's life. But untangling the web of murky secrets, family ties and old betrayals that conceals the truth will prove to be a dangerous pursuit for Eldritch and Stephen. Before long, a mysterious enemy is doing everything possible to stop the truth emerging - at whatever cost...
