Ellery Queen first appeared in June, 1929 in The Roman Hat Mystery, followed by The French Powder Mystery (1931), and The Dutch Shoe Mystery (1932). The plot in the fourth story, The Greek Coffin Mystery (1932), actually pre-dates The Roman Hat Mystery and reveals a younger, less-experienced Ellery Queen. We readers see an overly confident Ellery Queen stumble in his deductions and are led through not one, but a several flawed solutions.
Not only is this "younger and cockier" Ellery Queen misled and chastised, but it will be a rare reader indeed that does not likewise become ensnared in faulty deductions and erroneous conclusions. Ellery Queen regains any lost prestige in his final, remarkable deductions that lead unerringly to the actual solution.
