This is the second in a series of pacy mystery-adventure stories for 9+ readers, set in the seamy, smoggy underworld of Victorian London. A new sensation grips London - a poisoner who strikes without a trace, leaving victims mad with terror...and then dead. Is there a cure for the BLACK TERROR? To find out, Wild Boy and Clarissa must catch the killer. Their hunt will lead them from the city's vilest slums to its grandest palaces, and to a darkness at the heart of its very highest society. Dripping with atmosphere and gothic gore, Wild Boy and the Black Terror will appeal to fans of Sherlock Holmes, gothic horror and all things murderous and mysterious. Two former circus performers-turned-master detectives uncover clues when a poisoner begins stalking the streets of mid-nineteenth-century London and threatening the queen.
