What happens

On the third morning after the murder, Inspector Queen and Ellery rise early and, after a hasty breakfast, arrange to meet Louis Panzer and Mrs. Phillips at the Roman Theatre. They conduct a thorough search of the premises, with Ellery and Mrs. Phillips conversing on stage before disappearing. The Inspector searches the orchestra, lounge, and restrooms without finding the missing object. Panzer delivers a parcel from Cronin, and the Inspector hints that finding a certain object is crucial to the case. Meanwhile, Detective Hagstrom reports that Angela Russo has entered Benjamin Morgan's office, prompting the Inspector to order her detained.

Themes in this chapter

  • The Primacy of Rational Deduction

    Ellery's logical analysis of the missing hat—deducing that it left the theatre on a man's head, and that the man was either the murderer or an accomplice—exemplifies the theme of rational deduction.

  • The Relentless Quest for Truth

    The Queens' early-morning search of the theatre, the Inspector's meticulous examination of every corner, and the pursuit of Angela Russo all underscore the relentless pursuit of truth.

Key passages

  • leads us inevitably, to my staggering mind, to the third fundamental conclusion: that Monte Field’s hat left the theatre in the most natural manner in the world: id est , by way of some man’s head, its owner being garbed in appropriate evening-clothes!

    Ellery concludes that the only logical way Monte Field's hat left the theatre was on the head of a man wearing evening clothes.

    Ellery presents a key deduction about the missing hat.

  • If he was the murderer, we have definitely established the sex and also the fact that our man was wearing evening-clothes that night—perhaps not a very illuminating point, since there were scores of such men in the theatre. If he was only an accomplice, we must conclude that the murderer was one of two possibilities: either a man dressed in ordinary clothes, whose possession of a tophat as he left would be patently suspicious; or else a woman, who of course could not sport a tophat at all!

    Ellery reasons that the hat-wearer is either the killer in evening dress or an accomplice, in which case the murderer must be a man in ordinary clothes or a woman.

    Ellery expands on the implications of the hat's departure.

  • A half hour ago she thought she’d given me the slip—she hopped into a cab and beat it downtown. … And say, Inspector—just three minutes ago I saw her enter Benjamin Morgan’s office!

    Detective Hagstrom reports that Angela Russo evaded him briefly and then entered Benjamin Morgan's office.

    Hagstrom's surveillance reveals a new connection between Angela Russo and Benjamin Morgan.
