The Tiger in the Smoke (Classic Crime)

A fog is creeping through the weary streets of London—so too are whispers that the Tiger is back in town, undetected by the law, untroubled by morals. And the rumors are true: Jack Havoc, charismatic outlaw, knife-wielding killer, and ingenious jail-breaker, is on the loose once again.

As Havoc stalks the smog-cloaked alleyways of the city, it falls to Albert Campion to hunt down the fugitive and put a stop to his rampage—before it’s too late . . .
