The Store of the Worlds by Robert Sheckley

The Store of the Worlds by Robert Sheckley (Playboy, September 1959)1 opens with Mr Wayne passing a pile of rubble and coming to a tumbledown building at the end, The Store of the Worlds. Inside, Wayne meets the proprietor, Mr Tompkins, who can supposedly transport people (by means of the rusty hypodermic needle on the table, and “certain gadgets” in the back of the store) to the world of their deepest desires. Tomkins gives a “Many Worlds” explanation to Wayne:

“What happens then?” Mr. Wayne asked.
“Your mind, liberated from its body, is able to choose from the countless probability worlds which the earth casts off in every second of its existence.”
Grinning now, Tompkins sat up in his rocking chair and began to show signs of enthusiasm.
“Yes, my friend, though you might not have suspected it, from the moment this battered earth was born out of the sun’s fiery womb, it cast off its alternate-probability worlds. Worlds without end, emanating from events large and small; every Alexander and every amoeba creating worlds, just as ripples will spread in a pond no matter how big or how small the stone you throw. Doesn’t every object cast a shadow? Well, my friend, the earth itself is four-dimensional; therefore it casts three-dimensional shadows, solid reflections of itself, through every moment of its being. Millions, billions of earths! An infinity of earths! And your mind, liberated by me, will be able to select any of these worlds and live upon it for a while.”

The rest of this lengthy but absorbing setup goes on to cover the cost of the service, which is very high, and the health implications (a year in the world of desire costs ten years of the traveller’s life as there is a strain on the nervous system). Then, when Wayne asks if the transition can be made permanent, Tompkins says he is researching that possibility using the money he gets from selling the service.
Wayne eventually tells Tompkins that he needs to give it some thought, and the story cuts to his journey home to Long Island. There we see that Wayne has a wife called Janet, a son called Tommy, and a comfortable middle-class existence. Over the following days, and against the background of his work on Wall Street and a sailing trip with his son Tommy, Wayne thinks about Mr Tompkins, The Store of the Worlds, and the sort of world he might desire.
The final scene of the story cuts back to the store, where Wayne is waking up. Tompkins asks him if he is okay and whether or not he wants a refund. Wayne replies that the experience was quite satisfactory but, when Tompkins probes further, Wayne will only say that his world of desire was in the recent past.
The story closes with Wayne paying Tompkins for the trip with “a pair of army boots, a knife, two coils of copper wire, and three small cans of corned beef” before he leaves the store:

[Wayne] hurried down to the end of the lane of gray rubble. Beyond it, as far as he could see, lay flat fields of rubble, brown and gray and black. Those fields, stretching to every horizon, were made of the twisted corpses of buildings, the shattered remnants of trees and the fine white ash that once was human flesh and bone.

We realise that Wayne’s comfortable, unexceptional middle-class life with his wife and son was the world he desired, and that he is actually the survivor of a nuclear war. The few remaining paragraphs of the story hint at what this entails, and ends with Wayne resolving to get back to his shelter before the rats come out and he misses his potato ration.
The story’s ending is a gut punch, even if you guess what is coming before you get to the reveal (I figured out where it was going just before Wayne handed over the payment2).
A very good—and well-constructed—story,3 and one that makes you reflect that there are much worse options than living in modern day Western society, for all its failings.
**** (Very Good). 2,400 words. Story link.

1. This story was first published under the title The World of Heart’s Desire.

2. There are several clues before the reveal: the rubble strewn street, the dilapidated building, the rusty hypodermic, and the year Wayne spends thinking about whether or not to take the trip (the experience is described as a year long in the setup).

3. I’d definitely put this in a Best of Robert Sheckley collection, along with Specialist and Pilgrimage to Earth.
