Crossover Cover: Nightingale's Lament

John Taylor is hired to investigate a singer known as the Nightingale, whose singing inspires suicide. Appearing or mentioned are: a new edition of The King in Yellow (a play from Robert W. Chambers’ book of the same name, which was incorporated into the Cthulhu Mythos by H. P. Lovecraft); the password “Swordfish” to get into a nightclub (the password to a speakeasy in the Marx Bros. film Horse Feathers); lots of monkeys doing manual labor, some of whom still have their wings (from L. Frank Baum's The Wizard of Oz); combat magicians (a reference to Warren Ellis’ comic book Gravel); Nicholas Hob (from Green’s book Drinking Midnight Wine); miller medallions (from the comic book Grimjack); Julien Advent, the timelost Victorian Adventurer (meant to be Adam Adamant from the BBC TV series Adam Adamant Lives!); phasers and photon torpedoes (from Star Trek); and the Murder Masque (said to be the villain responsible for Julien Advent becoming timelost, which means he is intended to be the Face, the main villain from Adam Adamant Lives!).
