Harlequin's Lane - a Harley Quin Short Story

While visiting the rather dull, conventional, country home of John and Anna Denman, Mr. Satterthwaite unexpectedly meets Mr. Quin on a narrow road called Harlequin's Lane behind the house. Locally, it's known as Lover's Lane. While exploring the lane, Satterthwaite meets Molly Stanwell and learns that there's to be an entertainment, a masquerade, that evening. Even Satterthwaite can't foresee the impact that Quin will have on the Denmans, and indeed, on himself and everyone present. Librarian's note #1: this short story was published in 'Story-Teller' magazine (1927) and then in the print anthology 'The Mysterious Mr. Quin' which was first published in 1930. Librarian's note #2: the print anthology contains 12 Mr. Quin short stories. Besides those, there are two more found in other collections: 'The Love Detectives,' and 'The Harlequin Tea Set.' Mr. Satterthwaite also appears in 'Three Act Tragedy' and 'Dead Man's Mirror.' All by Agatha Christie, of course! Librarian's note #3: the entries for all fourteen Mr. Quin short stories can be found on GR by searching: 'a Harley Quin short story.' Details such as characters and settings are included for each.
