Joseph Berg was due to meet his 'contact' at a pub in London one rainy Friday evening. Unfortunately for Berg and the contact, someone got to the spy first and cut his throat - and Berg both witnessed the murder and became the chief suspect.

In his desperation Berg approaches Richard Monk, a young solicitor with a taste for investigation, and Alan Scarby, a barrister who has his work cut out to defend Berg both at the Old Bailey and in Israel.
