In 1947, former police officer Rafael Jones has just opened his own private investigation business, and he already has two cases. One has him helping Interpol locate some stolen Russian art from the time of the last czar. The other has him checking out a mysterious cult.
Little does he know the two cases are connected and will bring him face to face with the legendary mad monk of Russia who supposedly died in 1916.
Will Rafael's world, or his very existence, ever be the same again?
