The inspector tells her that despite earning a fortune from the auction where he sold everything in the apartment, Charles was travelling on the train practically a beggar. Apart from a four passports, four thousand francs in his wallet, a letter to Regina, a notebook, a toothbrush and a toothpowder, Charles wasn't carrying anything else. This alarms the police. And us!
During Charles's funeral, there is more cause for concern. Practically unattended, Regina is confused to find just three visitors who act weird in front of Charles's body. One keeps sneezing and two poke him to assure that he is in fact dead.
Tex, Scobie and Leopold are constantly accosting her to get their money back. Regina is dumbfounded and scared because she knows nothing about the money. And there is this Peter Joshua is too attractive for her to be in her right senses but who is also a wee bit mysterious. A winning stroke by the director is when he shows Joshua to be one among the goons, in the guise of Alexander Dyle, Carson's brother. He too wants his brother's share of the money and is hoodwinking Regina for it. He is the dapper one that has the charms to befriend Regina. But the problem is that while all these men are aiming towards one thing, none of them can trust each other.
A mind-boggling thriller, Donen makes it even more sharp with the sudden twists hurled at us every second. Like every time Cary Grant's character reveals that he is not a certain person and that he was lying to Regina, we start suspecting him even more. Like when Joshua (now Canfield) tastes the toothpowder and declares it to be heroine, I gasp and say, "So this is where the money is!" But the next moment he draws a straight face and says, "Peppermint flavoured heroine." And I'm like: "Oh it's back to square one again. The chase continues!" Regina is caught in a mesh out of which she cannot come out of her own free will. She wants to believe Joshua, but should she? Who is killing all these men? And is Carson Dyle really dead?
