Albert Campion is sailing home when he saves the life of fellow passenger, Judge Crowdy Lobbett. Hunted by the notoriously deadly Simister gang, it seems as though the judge's troubles have followed him from America.
Determined to catch the infamous gang leader, Albert bundles the judge, along with his son Marlowe and beautiful daughter Isopel, to the manor at Mystery Mile, where he hopes to lure the villain out into the open. But the safe haven of Mystery Mile is soon invaded by danger, and when people start disappearing, the race to uncover the enigma of their enemy's true identity becomes ever more urgent. Mystery Mile, first published in 1930, is the second Margery Allingham novel starring eccentric and well-loved amateur sleuth, Albert Campion.
