Jack of Spies

Jack McColl is a globe-trotting salesman for a luxury car firm. He is also a part-time spy for the fledgling Secret Service on the eve of the First World War, doing London's bidding wherever internal or external enemies threaten the security of the British Empire. As 1913 ends he is in China, checking out the German naval base at Tsingtao between automobile demonstrations in Peking and Shanghai.
