The Clock is Tight. The Useful Spy, #9

Miller is sent to track a biological threat that has been placed inside a European city by a network that has no ideology - only commerce. The buyers are unknown. The clock is tight. And for the first time, Sir Harold is not in London when the clean phone rings - he is in the field, and he is in danger. Miller must choose between the operation and the man. Miller heads to Vienna to start the search.
At the Freud University he meets a visiting professor with a story to tell. Time to take a train through Europe desperately looking for clues and meeting violence and danger along the way.
