A duty of care

Jonas Merrick has been banished to the Post Room of Thames House. There, he is expected to pass his remaining days before inevitable retirement. In a Russian gulag, an MI6 agent has developed an unlikely passion for a prisoner and has come up with an ingenious plan to free her. The key: a ruthless Albanian gang laundering the dirty money of the Russian elite. Merrick, the only agent with the experience to help, is brought back once again to intercept the Albanian courier until an exchange is organised by the Russians.
