Alfred Hitchcock described this, his third feature, as the first to display the patented Hitch 'touch' (it was also the first to feature a cameo by the director). The foggy streets of London have fallen prey to the 'Avenger' - an unknown killer whose victims are all blonde women. When a handsome lodger (Ivor Novello) arrives at a local boarding house, his suspicious behaviour leads to him being accused of the crimes and hotly pursued by a lynch mob out for justice. But is he really guilty? Composer Nitin Sawhney provides a new musical score for this version of the film.
