The main characters are Murchison and Leeds, British gentlemen who investigate the strange phenomena besetting Queen Victoria's Great Britain in the 1870s. Leeds, from upper middle-class, is the careful planner, while Murchison, having risen from near-poverty to become a successful barrister, is more impetuous. Together they take on the unknown, of this world and almost certainly others.
In "The Grey Men Cometh," Murchison and Leeds are asked to help a young lady whose nights are filled with a horror so unimaginably vile, she is in danger of taking her life rather than speak about it.
