SF editor Mann (The Solaris Book of New Science Fiction
) sets this leisurely mystery, published in the U.K. by Snowbooks in 2008, in an alternate 1901 London where steam-powered taxicabs fill the streets and brass automatons have begun to replace human labor. Sir Maurice Newbury, British Museum anthropologist and occult connoisseur, and his Watsonesque assistant, Miss Veronica Hobbes, are summoned to investigate the crash of a cyborg-piloted helium zeppelin. Meanwhile, a plague is spreading through London's poorer quarters, turning everyday citizens into bloodthirsty, zombielike “revenants” and threatening the stability of the Empire. Mann's stiff-upper-lipped Victorians chat at great length over cups of Earl Grey and occasionally whack zombies and robots in arduous action passages, and the unnecessary details and painfully stilted dialogue bring nothing fresh to the steampunk subgenre.
