Jack Havoc, jail-breaker & knife artist, is on the loose on the streets of London once again. In the faded squares of shabby houses, in the furtive alleys & darkened pubs, the word is out that the Tiger is back in town, more vicious & cunning than ever. It falls to Albert Campion to pit his wits against the killer & hunt him down through the city's November smog before it is too late.
