The Parachute Courier

Published in Adventure, October, 1933.
The question of who has been using tiny synthetic moles on couriers has perplexed the Deuxieme Bureau, especially after the third incident. The fact that it was related to a plot by a traitor to disrupt the food lines to the French troops made solving the matter of prime importance. While the plan to launch a great number of operatives along the border to try to catch the man was started, Fox Elton had a more direct approach - parachute into the arms of the enemy.
