Afterwards, it was easy to see how it had happened. Someone had fired through the open doorway. One shot had caught Mark Verinder between the eyes. The other had hit Deirdre Masson and though she, too, looked dead, she wasn't.
And the testimony was clear enough-up to a point. Motive, time, the right gun. Everything seemingly was explained until Inspector Upjohn remembered the March Hare and the Mad Hatter, and that gave him the true solution.
