Christopher Quarles: College Professor and Master Detective

In the genteel streets of Blenheim Square, where tidy garden squares and well‑kept townhouses suggest a quiet, respectable life, a sudden death shatters the calm. Detective Murray Wigan, a young professor with a reputation for keen observation, is summoned to No. 12 after the housekeeper discovers the body of the affluent Mr. Ratcliffe in his study. The scene is oddly pristine: a burning lamp, a sapphire resting on a blotting pad, and a set of delicate ivory boxes nested one inside another like a puzzling Russian doll.

Enter Christopher Quarles, the enigmatic elder in a rust‑stained coat and round goggles, whose cryptic invitation hints at a deeper connection to the case. As Quarles silently surveys the arrangement of the boxes and the lifeless figure, Wigan must decide whether to trust this mysterious ally. Together they begin to untangle a curious blend of academic insight and detective skill, setting the stage for a cerebral puzzle that promises more intrigue than the tranquil square ever expected.
