The Coming of Mr. Quin — Agatha Christie

It's dark and cold, with snow drifts everywhere, when Mr. Harley Quin appears at the door of Royston Hall under the premise that his car has broken down.

Once inside, he finds a small party celebrating the new year. Quin remarks that he knew the previous owner of Royston Hall. He then launches into the tragic tale of the former occupants leading to a dramatic change in the perceptions of the current inhabitants. But has Mr. Quin's revelation come too late?

‘The Coming of Mr Quin' was first published as ‘The Passing of Mr Quinn' in Grand Magazine, March 1923 and then in the print anthology 'The Mysterious Mr. Quin.'
