Helen answered. “She came around noon. They went to lunch together and then were going to the rodeo.”

“Thank you. So all she had to do was to make some excuse and see that he went to the rodeo alone. It was an ideal selection — Madison Square Garden, that enormous crowd. Then she met Arthur Howell somewhere near, having arranged for him to be dressed as her husband was dressed, and brought him here. She was driving her car — or her husband’s car. They left here a little before five o’clock. Between here and Forty-second Street he got out and went to Grand Central to take a train to White Plains. A woman who could persuade a man to help her kill her husband could surely persuade him to take a train to White Plains.”

Fritz brought beer, and Wolfe opened a bottle and poured.

“Then she continued to Fiftieth Street and met her husband as he left the rodeo, and they drove to Westchester, having an appointment to see Mr. Blaney at his place there. She talked her husband out of that, left him at a place called Monty’s Tavern, drove somewhere, probably the White Plains railroad station, met Arthur Howell there as arranged, drove to an isolated spot probably previously selected, turned off the road into an orchard, killed Mr. Howell or knocked him unconscious with whatever she used for that purpose, removed his clothing, and ran the car over him to obliterate his face.”

A noise came from Helen Vardis. She had obliterated her own face by covering it with her hands. That gave Joe an excuse to touch her again, which he did.

“Granted her basic premise,” Wolfe went on, “she couldn’t very well have been expected to let Arthur Howell continue to live. She would never have had a carefree moment. What if Mr. Goodwin or I had met him on the street? That thought should have occurred to him, but apparently something about Mrs. Poor had made him quit thinking. There are precedents. Since she was good at detail, I presume she spread his coat over his head so as to leave no telltale matter on her tires. What she then did with the clothing is no longer of interest, at least not to me.”

He drank beer. “She proceeded. First to Mr. Blaney’s place to make sure, by looking through windows, that he was alone there, so that she could safely say that she had gone to see him and couldn’t find him. Again she was providing for all contingencies. If Arthur Howell’s body was after all identified, known as that of a man who was with the Beck Products Corporation and had access to those capsules, it would help to have it established that Mr. Blaney had not been at home during the time that Arthur Howell had been killed. It wouldn’t surprise me if a good search around Mr. Blaney’s place discovered Mr. Howell’s clothes concealed — no, that wouldn’t do, since they were the same as Mr. Poor’s. She wouldn’t make that kind of mistake.”

He emptied the glass. “The rest is anticlimax, though of course for her it was the grand consummation. She returned to Monty’s Tavern, told her husband Mr. Blaney had not been at home, dined with him, drove back to New York and went to their apartment, and got him a nice fresh cigar from a new box. Everything worked perfectly. It sounds more complicated than it really was. Such details as making sure that no photographs of her husband would be available for the newspapers had no doubt been already attended to.”

“That receipt you signed,” Cramer growled.

“What? Oh. That gave her no difficulty. Arthur Howell gave the receipt to her, naturally, and she put it in her husband’s pocket. That was important. It was probably the first thing she did after the cigar exploded.”
