Arthur Machen (1863-1947) was a Welsh author and mystic, best known for his influential supernatural, fantasy and horror fiction.
'The Lost Club' is a supernatural adventure story. Stranded in London during the summer vacation period and caught up in a sudden rain shower, two friends sought shelter in an archway. One of them vaguely remembered having heard that there was a club down this alleyway. From this point events become very strange.
A mutual friend appears, who is able to introduce the two into the mysterious club. All the members are well known figures in London society...and they are all there for a bizarre and terrifying ceremony. Each member must open an old book, and whoever turns up the black page will face an unknown and horrifying fate.
