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:
Boswell met her on December 28, 1763, possibly at Baron Sporck's in The Hague. In a memo he wrote that Madame Maasdam told you how la Comtesse was taken to Utrecht, as there were strange suspicions. "She is a little galante, but do not whisper it".1
