Nicholas Everitt, British Secret Service During the Great War
“ For let it not be forgotten that to accept an appointment under the Foreign Secret Service in war time is no feather-bed occupation. The smallest slip, the slightest indiscretion, and one's doom is sealed. Only a man to whom life was as nothing if risking it would help his country, would dare to undertake such perilous work. It is indeed the finest and most thrilling recuperative tonic in the world for anyone weary of life's monotonies. It commands the highest courage, the clearest understanding, the greatest ability and cleverness, never-flagging persistence, and an ever-prevailing optimism. ”
