Dr. Yen Sin is a three-issue fiction anthology magazine that was originally published from May through October 1936 by Popular Publications, featuring lead stories by Donald E. Keyhoe about the plots of the titular doctor, a Fu Manchu-type character and mastermind of the "Invisible Empire", and his adversary Michael Traile, "the Man Who Never Slept" (or "Man Who Never Sleeps"), a spy who suffered chronic insomnolence from childhood after an operation to repair a skull fracture caused irreparable brain damage. The magazine was a follow-up to the earlier title The Mysterious Wu Fang by the same publisher that had ended in February 1936.


#1, May & June 1936

  • Note to Our Readers - An Introduction
  • Keyhoe, Donald E., The Mystery of the Dragon's Shadow

    Out of the teeming turbulent East had come Dr. Yen Sin — saffron-skinned wizard of crime — bringing to the capital of the West all the ancient Devil's-lore at his command — and a horde of Asian Hell-born to help him spawn it. But Michael Traile — the Man Who Never Slept — had crammed into his own keen brain the means to cope with the sinister doctor. For he knew even the secrets of the Dragon's Shadow and how to penetrate the yellow murder fog that had descended on the capital to mingle its blood-wisps with the mist from the Potomac.

#2, July & Aug. 1936

  • Feng Tai Sui Feng
  • Keyhoe, Donald E., The Mystery of the Golden Skull

    Moving east from the nation's capitol at Washington, Dr. Yen Sin, saffron-skinned scourge of the Orient, sets up his hell-base in New York and under the banner of the Golden Skull, once again locks horns with Michael Traile, the Man Who Never Sleeps, and his partner Eric Gordon. What is the ghastly doom he brings with him to turn living men to rainbow-colored dust? Why should the flowers in his corpse garden have their heads removed, only to be sewed on again — backwards — by the surgeon mandarin?

#3, Sept. & Oct. 1936

  • Fei Lu Fei Ma
  • Keyhoe, Donald E., The Mystery of the Singing Mummies

    To the teeming city of the Golden Gate the sinister Yen Sin had transferred his base of operations — and there, under cover of the fog-shrouded Frisco night, he set loose the mostly ghastly weapon in his whole armory of mysterious torture devices — the curse of the Singing Mummies. In ten minutes by the clock, to the accompaniment of that insidious, eery music, living men and women underwent their ghastly metamorphosis, became fit occupants for the coffin-cases of ancient Egypt. How could the saffron-skinned crime-emperor accomplish the change? How could even Michael Traile, the Man Who Never Slept, hope to cope with the devilish Thing?

A fourth issue was solicited, promising a new Keyhoe story, The Case of the Faceless Men, but this was never published, as the magazine ceased publication after the third issue.
