Among the famous historical hauntings, we must not forget to mention the famous Cock Lane Ghost which occurred about 1760. According to a brief paragraph printed in the London Ledger, 1762, we read that:

“For some time a great knocking having been heard in the night, at the officiating parish clerk’s of St. Sepulchre’s, in Cock Lane near Smithfield, to the great terror of the family, and all means used to discover the meaning of it having failed, four gentlemen sat up there last Friday night, among whom was a clergyman standing withinside the door, who asked various questions. On his asking whether anyone had been murdered, no answer was made; but on his asking whether anyone had been poisoned, it knocked one and thirty times. The report current in the neighborhood is that a woman was some time ago poisoned, and buried in St. John’s Clerkenwell, by her brother-in-law.”

These knockings and phenomena occurred for a considerable time, until the whole community became interested in the manifestations. While various theories were advanced at the time—and since—to explain this ghost, no definite conclusion has ever been arrived at.
