Aboard the plane from Paris to Croydon are eleven passengers, two stewards, and one maid.
Jane Grey, a manicurist, won one of the lesser prizes in the lottery and used her winnings to visit Le Pinet and try her hand at roulette. The Countess of Horbury is very familiar with the casino floor herself — much, much too familiar than Lord Horbury’s pocket book will support. The Hon. Venetia Kerr, who’s nothing but country life and horse-sense, would have made Horbury a better match, as they both know, but there’s no way the Countess would grant a divorce. On the male side are the Duponts, father and son archeologists, too engrossed in an argument about the dating of near-eastern pottery to notice much. Clancey is busy in his own mind, as well — he’s a murder mystery author plotting a new book. Ryder is making moon eyes at Jane, sitting opposite him, and doing little else. Medical doctor Bryant cleans his beloved flute, while dental doctor Gale laments that nobody pays any attention to dentists. Finally, Hercule Poirot sits bundled up almost to his eyes, and two rows back, Madame Griselle, that infamous Parisian money-lender and blackmailer, sloops forward over her coffee cup, dead from a snake venom dart apparently launched at her neck from a South American blowpipe.
One of the recurring questions is how nobody on the plane saw such a farcical proceeding of somebody getting up, loading a blowpipe with a feathered dart, taking aim at Griselle, and blowing. What distraction could have been so great to cover that? Of course, that’s just what the murder wants everyone to waste their time on — that’s why they planted the blowpipe. The poison was simply injected directly into the blackmailer’s vein by someone who could get close enough to do it without attracting attention. I didn’t need all that many clues to spot the culprit. The way the character is written and the way they behave instantly from the moment the crime is discovered and until the reveal marks them as the murderer. For that matter, just reading the brief character introductions above, you’ve probably spotted who did it, too.
