When a series of gruesome murders coincides with the arrival of Dr Marvello's Travelling Circus the performers find themselves caught up in some rather sinister goings-on.

Prometheus the strongman winds up behind bars and it falls to ringmaster and master conjuror Cornelius Quaint, ably assisted by his Eskimo valet Butter, to investigate the killings and to clear his name.

But Quaint, an irresistable mix of Sherlock Holmes and Harry Houdini, soon finds that these seemingly random killings are actually linked to dark secrets from his own past. Secrets that he may not be prepared to face.

The Equivoque Principle is a fantastic adventure inspired by the penny dreadfuls and newspaper serials of the Victorian age and the first in a great new series.
