James Boswell died in 1795 believing he had touched and kissed a cache of Shakespeare's original letters and papers discovered by a Mr. Ireland. His friend, Edmond Malone, publicly exposed the lot as a forgery just a year later.
Life with Boswell:
On October 10, 1764 Boswell described O'Carroll in his journal as “an obliging sort of man, but very formal. He was just Mr. Carron at Utrecht in regimentals.”
