"I want you to shuffle the cards thoroughly, then lay out a Canfield solitaire, dealing from left to right, then play it out, three cards at a time, going through the deck again and again, until you are stuck and can't go any farther." "Okay. What's the gag?"
"After you have shuffled and cut, I want you to riffle the cards through once, holding them up so that Joan gets a quick glimpse of the index on each card. Then wait a moment."
Silently he did what he had been asked to do. Joan checked him. "You'll have to do it again, Ben. I saw only fifty-one cards."
"Two of them must have stuck together. I'll do it more carefully." He repeated it.
"Fifty-two that time. That's fine."
"Are you ready, Joan?"
"Yes, Phil. Take it down; hearts to the six, diamonds to the four, spades to the deuce, no clubs."
Cobum looked incredulous. "Do you mean that is the way this game is going to come out?"
"Try it and see."
He dealt the cards out from left to right, then played the game out slowly. Joan stopped him at one point. "No, play the king of hearts' stack into that space, rather than the king of spades. The king of spades play would have gotten the ace of clubs out, but three less hearts would play out if you did so." Cobum made no comment, but did as she told him to do. Twice more she stopped him and indicated a different choice of alternatives.
The game played out exactly as she had predicted.
Coburn ran his hand through his hair and stared at the cards. "Joan," he said meekly, "does your head ever ache?"
"Not from doing that stuff. It doesn't seem to be an effort at all."
"You know," put in Phil, seriously, "there isn't any real reason why it should be a strain. So far as we know, thinking requires no expenditure of energy at all. A person ought to be able to think straight and accurately with no effortI've a notion that it is faulty thinking that makes headaches."
"But how in the devil does she do it, Phil? It makes my head ache just to try to imagine the size of that problem, if it were worked out longhand by conventional mathematics."
"I don't know how she does it. Neither does she."
"Then how did she leam to do it?"
"We'll take that up later. First, I want to show you our piece de resistance"
"I can't take much more. I'm groggy now."
"You'll like this."
"Wait a minute, Phil. I want to try one of my own. How fast can Joan read?"
"As fast as she can see."
"Hmm ". The doctor hauled a sheaf of typewritten pages out of his inside coat pocket. "I've got the second draft of a paper I've been working on. Let's try Joan on a page of it. Okay, Joan?"
He separated an inner page from the rest and handed it to her. She glanced at it and handed it back at once. He looked puzzled and said:
"What's the matter?"
"Nothing. Check me as I read back." She started in a rapid singsong, " 'page four. now according to Cunningham, fifth edition, page 547: "Another strand of fibres, videlicet, the fasciculus spinocerebellaris (posterior), prolonged upwards in the lateral fumiculus of the medulla spinallis, gradually leaves this portion of the medulla oblongata. This tract lies on the surface, and is "
"That's enough, Joan, hold it. God knows how you did it, but you read and memorized that page of technical junk in a split second." He grinned slyly. "But your pronunciation was a bit spotty. Grandfather Stonebender's would have been perfect."
"What can you expect? I don't know what half of the words mean."
"Joan. how did you leam to do all this stuff?"
"Truthfully, Doctor, I don't know. It's something like learning to ride a bicycle you take one spill after another, then one day you get on and just ride away, easy as you please. And in a week you are riding without handle-bars and trying stunts. It's been like that I knew what I wanted to do, and one day I could. Come on, Phil's getting impatient."
Ben maintained a puzzled silence and permitted Phil to lead him to a little desk in the comer. "Joan, can we use any drawer? OK. Ben, pick out a drawer in this desk, remove any articles you wish, add anything you wish. Then, without looking into the drawer, stir up the contents and remove a few articles and drop them into another drawer. I want to eliminate the possibility of telepathy."
"Phil, don't worry about my housekeeping. My large staff of secretaries will be only too happy to straighten out that desk after you get through playing with it."
"Don't stand in the way of science, little one. Besides," he added, glancing into a drawer, "this desk obviously hasn't been straightened for at least six months. A little more stirring up won't hurt it,"
"Humph! What can you expect when I spend all my time learning parlor tricks for you? Besides, I know where everything is."
"That's just what I am afraid of, and why I want Ben to introduce a little more of the random element if possible. Go ahead, Ben."
When the doctor had complied and closed the drawer, Phil continued, "Better use pencil and paper on this one, Joan. First list everything you see in the drawer, then draw a little sketch to show approximate locations and arrangement."
"OK." She sat down at the desk and commenced to write rapidly:
One large black leather handbag
Six-inch ruler
Ben stopped her. "Wait a minute. This is all wrong. I would have noticed anything as big as a handbag.У
She wrinkled her brow. "Which drawer did you say?"
The second on the right."
"I thought you said the top drawer."
"Well, perhaps I did."
She started again; Brass paper knife
Six assorted pencils and a red pencil
Thirteen rubber bands
Pearl-handled penknife
"That must be your knife, Ben. It's very pretty; why haven't I seen it before?"
"I bought it in San Francisco. Good God, girl. You haven't seen it yet."
One paper of matches, advertising the Sir Francis Drake Hotel
Eight letters and two bills
Two ticket stubs, the Follies Burlesque Theatre "Doctor, I'm surprised at you."
"Get on with your knitting."
"Provided you promise to take me the next time you go."
One fever thermometer with a pocket clip
Art gum and a typewriter eraser
Three keys, assorted
One lipstick. Max Factor #3
A scratch pad and some file cards, used on one side
One small brown paper sack containing one pair stockings, size nine, shade Creole. "I'd forgotten that I had bought them; I searched all through the house for a decent pair this morning."
"Why didn't you just use your X-ray eyes, Mrs. Houdini?"
She looked startled. "Do you know, it just didn't occur to me. I haven't gotten around to trying to use this stuff yet."
"Anything else in the drawer?"
"Nothing but a box of notepaper. Just a sec: I'll make the sketch." She sketched busily for a couple of minutes, her tongue between her teeth, her eyes darting from the paper toward the closed drawer and back again. Ben inquired,
"Do you have to look in the direction of the drawer to see inside it?"
"No, but it helps. It makes me dizzy to see a thing when I am looking away from it."
The contents and arrangement of the drawer were checked and found to be exactly as Joan had stated they were. Doctor Cobum sat quietly, making no comment, when they had finished. Phil, slightly irked at his lack of demonstrativeness, spoke to him.
"Well, Ben, what did you think of it? How did you like it?"
"You know what I thought of it. You've proved your theory up to the hilt but I'm thinking about the implications, some of the possibilities. I think we've just been handed die greatest boon a surgeon ever had to work with. Joan, can you see inside a human body?"
