Rumor tells of a murderer who sent fear throughout New York City one stormy summer—Icepick Thompson, who strikes only on rainy days and stabs his targets relentlessly. As the papers fill up with articles and speculation about the serial murderer (the Daily Days leading the pack), police suspicion turns to Graham Specter and his band of ne’er-do-wells. Meanwhile, Elmer is quickly swept up in the scandal during a visit to New York, and with several of their associates falling victim to the attacks, the Gandors close in on the heart of the incident...
