And on this fantastic occasion it happened. In the half-opened drawer that pressed against Benny's tummy, just below the level of the table and out of range of Mr. Tombs's glassy stare, was another brown paper parcel exactly similar in every respect to the one which Benny was finishing off. Outwardly, that is. Inside, there was a difference; for whereas inside the parcel which Benny had prepared before Mr. Tombs's eyes there were undoubtedly two thousand authentic one-pound notes, inside the second parcel there was only a collection of old newspapers and magazines cut to precisely the same size. And never before in Benny's career, once the fish had taken the hook, had those two parcels failed to be successfully exchanged. That was what the providentially falling window was arranged for, and it constituted the whole simple secret of the green goods game. The victim, when he got home and opened the parcel and discovered how he had been swindled, could not make a complaint to the police without admitting that he himself had been ready to aid and abet a fraud; and forty-nine times out of fifty he would decide that it was better to stand the loss and keep quiet about it. Elementary, but effective. And yet the whole structure could be scuppered by the unbelievable apathy of a victim who failed to react to the stimulus of a loud bang as any normal human being should have reacted.
"The-the window seems to have fallen down," Benny pointed out hoarsely; and felt like a hero of a melodrama who has just shot the villain in the appointed place at the end of the third act, and sees him smilingly declining to fall down and die according to the rehearsed script.
"Yes," agreed Mr. Tombs cordially. "I heard it."
"The-the sash-cords must have broken."
"Probably that's what it was."
"Funny thing to happen so-so suddenly, wasn't it?"
"Very funny," assented Mr. Tombs, keeping up the conversation politely.
Benny began to sweat. The substitute parcel was within six inches of his hovering hands: given only two seconds with the rapt stare of those unblinking eyes diverted from him, he could have rung the changes as easily as unbuttoning his shirt; but the chance was not given. It was an impasse that he had never even dreamed of, and the necessity of thinking up something to cope with it on the spur of the moment stampeded him to the borders of panic.
"Have you got a knife?" asked Benny, with perspiring heartiness. "Something to cut off this end of string?"
"Let me break it for you," said Mr. Tombs.
He stood up and moved towards the table; and Benny shied like a horse.
"Don't bother, please, Mr. Tombs," he gulped. "I'll-I'll --"
"No trouble at all," said Mr. Tombs.
Benny grabbed the parcel, and dropped it. He was a very fine strategist and dramatic reciter, but he was not a man of violence-otherwise he might have been tempted to act differently. That grab and drop was the last artifice he could think of to save the day.
He pushed his chair back and bent down, groping for the fallen parcel with one hand and the substitute parcel with the other. In raising the fallen packet past the table the exchange might be made.
His left hand found the parcel on the floor. His right hand went on groping. It ran up and down the drawer, sensitively at first, then frantically. It plunged backwards and forwards. His fingernails scrabbled on the wood . . . He became aware that he couldn't stay in that position indefinitely, and began to straighten up slowly, with a cold sensation closing on his heart. And as his eyes came up to the level of the drawer he saw that the dummy parcel had somehow got pushed right away to the back: for all the use it would have been to him there it might have been in the middle of the Arizona desert.
Mr. Tombs smiled blandly.
"It's quite easy, really," he said.
He took the parcel from Benny's nerveless hand, put it on the table, twisted the loose end of string round his forefinger, and jerked. It snapped off clean and short.
"A little trick of mine," said Mr. Tombs chattily. He picked up the parcel and held out his hand. "Well, Mr. Lucek, you must know how grateful I am. You mustn't let me keep you any longer from your-um-widow. Good-bye, Mr. Lucek."
He wrung Benny Lucek's limp fingers effusively, and retired towards the door. There was something almost sprightly in his gait, a twinkle in his blue eyes that had certainly not been there before, a seraphic benevolence about his smile that made Benny go hot and cold. It didn't belong to Mr. Tombs of the insurance office ...
"Hey-just a minute," gasped Benny; but the door had closed. Benny jumped up, panting. "Hey, you --"
He flung open the door, and looked into the cherubic pink fullmoon face of a very large gentleman in a superfluous overcoat and a bowler hat who stood on the threshold.
"Morning, Mr. Lucek," said the large gentleman sedately. "May I come in?"
