Bats in the Wall; or, The Mystery of Trinity Church-yard

A rejected marriage proposal involving a young bank clerk triggers a chain of criminal incidents and investigations: stolen silver dollars from Webster National Bank are discovered in a fish basket, prompting a determined detective to trace suspects through a shady saloon and the streets to Trinity church‑yard. The inquiry uncovers hidden passages, an iron door, bats nesting in a wall, a grim chamber, and a treasure hunt that links vanished individuals to a network of thieves and corrupt associates. Gradual discoveries unravel the mystery, expose multiple related crimes, and culminate in the thwarting and explanation of the central conspiracy.
