In the summer of 1936 author and occultist Dennis Wheatley assembled a collection of friends, scholars and fellow authors to play a game, a latter-day Decameron of sorts.  This group would catalogue the unseen underbelly of London. The city beneath the surface of the city, which most people never knew and those who did tried to forget.  The tales would, of course, be drawn from the members' imaginations, spun out of half-heard rumors and drunkard's lies. But as the game wore on it became clear to the group that there was more at hand than there seemed.

The collected works of these "Men of Mystery," as they were known, were thought lost during the war. But minutes of their society meetings were recently discovered by the estate of one of the members. They are presented here in unedited form.
