There’s no rest for Sherlock Holmes’s old foil Sholto Lestrade. The seventh of his sixteen adventures (Lestrade and the Deadly Game, p. 1091, etc.) sends the doughty inspector, convalescing from a broken leg he got in exiting the Titanic, to his fiancée Fanny Berkely’s peaceful home in Surrey – only to shatter the peace with a series of threatening letters linked to an attempt on the life of Fanny’s father, and to a more successful attempt on a fellow copper.
