King Of The Commandos

This is the 1st in the Gimlet series of war adventures, a companion to the Biggles series.
This is "an account of dangerous moments and exciting encounters in occupied France during the war. ... Leading the Commandoes is Captain Lorrington King, D.S.O., M.C., better-known to his thousands of admirers as Gimlet."
Biggles plays a very small, unspeaking, part in these adventures when he asks for a short time as the pilot conveying the team to missions.
