Mysteries of the Worm by Robert Bloch Zebra Books, Original Paperback, 1981 Condition: Very Good+ to Near Fine Here are collected for the first time all of Robert Bloch's short stories of the Cthulhu Mythos (influenced by H.P. Lovecraft). They appropriately number 13, published between 1935 and 1958; most originally appeared in Weird Tales. Lin Carter provides an Introduction. This first edition is fairly uncommon, since it was pubished by one of the smaller paperback imprints of the '80s. Light reading crease and bits of other light exterior wear; a small price written on the first page, along with a light bookstore stamp. Overall, though, a sharp, tightly bound copy.
