Madness runs in some families, in the Wraydons it practically gallops in this poky but generally good-looking pre-Victorian melodrama that marked everyone's favourite wicked uncle's return to the big screen after being obliged to confine his villainy to the stage for the duration of the War by official discouragement of horror films (although his thirties vehicles had continued to do the rounds in cinemas).
A whiskerless Tod Slaughter is only Spring Heeled Jack in name, since he skulks about rather than leaps and the action is actually set against the backdrop of the Napoleonic wars, over thirty years before the first alleged sightings of the 'historical' Jack in 1837.
