Paul Collins’ The Murder of the Century was briefly everywhere and I found a cheapo copy when I saw it linked with The Devil in the White City by Erik Larson, which is a surprisingly engaging piece of non-fiction (I preferred Dead Wake, ftr).
From the back cover:
On Long Island, a farmer finds a duck pond turned red with blood. On the Lower East Side, two boys discover a floating human torso wrapped tightly in oilcloth. Blueberry pickers near Harlem stumble upon neatly severed limbs in an overgrown ditch. The police are baffled: There are no witnesses, no motives, no suspects.
The grisly finds that began on the afternoon of June 26, 1897, plunged detectives headlong into the year’s most perplexing murder mystery. Seized upon by battling media moguls Joseph Pulitzer and William Randolph Hearst, the case became a publicity circus, as an unlikely trio—a hard-luck cop, a cub reporter, and an eccentric professor—all raced to solve the crime. What emerged was a sensational love triangle and an even more sensational trial.
