“All I wish to do, Miss Bond, is to make a few, simple little tests of your nervous condition. One of them we specialists call reaction time, and another is a test of heart action. Neither is of any seriousness at all, so I beg of you not to become excited, for the chief value consists in having the patient perfectly quiet and normal. After they are over I think I’ll know whether to prescribe absolute rest or a visit to Newport.”
She smiled languidly, as he adjusted a long, tightly fitting rubber glove on her shapely forearm and then encased it in a larger, absolutely inflexible covering of leather. Between the rubber glove and the leather covering was a liquid communicating by a glass tube with a sort of dial. Craig had often explained to me how the pressure of the blood was registered most minutely on the dial, showing the varied emotions as keenly as if you had taken a peep into the very mind of the subject. I think the experimental psychologists called the thing a “plethysmograph.”
Then he had an apparatus which measured association time. The essential part of this instrument was the operation of a very delicate stopwatch, and this duty was given to me. It was nothing more nor less than measuring the time that elapsed between his questions to her and her answers, while he recorded the actual questions and answers and noted the results which I worked out. Neither of us was unfamiliar with the process, for when we were in college these instruments were just coming into use in America. Kennedy had never let his particular branch of science narrow him, but had made a practice of keeping abreast of all the important discoveries and methods in other fields. Besides, I had read articles about the chronoscope, the plethysmograph, the sphygmograph, and others of the new psychological instruments. Craig carried it off, however, as if he did that sort of thing as an everyday employment.
“Now, Miss Bond,” he said, and his voice was so reassuring and persuasive that I could see she was not made even a shade more nervous by our simple preparations, “the game—it is just like a children’s parlour game—is just this: I will say a word—take ‘dog,’ for instance. You are to answer back immediately the first word that comes into your mind suggested by it—say ‘cat.’ I will say ‘chain,’ for example, and probably you will answer ‘collar,’ and so on. Do you catch my meaning? It may seem ridiculous, no doubt, but before we are through I feel sure you’ll see how valuable such a test is, particularly in a simple case of nervousness such as yours.”
I don’t think she found any sinister interpretation in his words, but I did, and if ever I wanted to protest it was then, but my voice seemed to stick in my throat.
He was beginning. It was clearly up to me to give in and not interfere. As closely as I was able I kept my eyes riveted on the watch and other apparatus, while my ears and heart followed with mingled emotions the low, musical voice of the girl.
I will not give all the test, for there was much of it, particularly at the start, that was in reality valueless, since it was merely leading up to the “surprise tests.” From the colourless questions Kennedy suddenly changed. It was done in an instant, when Miss Bond had been completely disarmed and put off her guard.
“Night,” said Kennedy. “Day,” came back the reply from Miss Bond.
“Automobile.” “Horse.”
“Bay.” “Beach.”
“Road.” “Forest.”
“Gate.” “Fence.”
“Path.” “Shrubs.”
“Porch.” “House.”
Did I detect or imagine a faint hesitation?
“Window.” “Curtain.”
Yes, it was plain that time. But the words followed one another in quick succession. There was no rest. She had no chance to collect herself. I noted the marked difference in the reaction time and, in my sympathy, damned this cold, scientific third degree.
“Paris.” “France.”
“Quartier Latin.” “Students.”
“Apaches.” Craig gave it its Gallicised pronunciation, “Apash.” “Really, Dr. Kennedy,” she said, “there is nothing I can associate with them—well, yes, les vaches, I believe. You had better count that question out. I’ve wasted a good many seconds.”
“Very well, let us try again,” he replied with a forced unconcern, though the answer seemed to interest him, for “les vaches” meant “the cows,” otherwise known as the police.
No lawyer could have revelled in an opportunity for putting leading questions more ruthlessly than did Kennedy. He snapped out his words sharply and unexpectedly.
“Chandelier.” “Light.”
“Electric light,” he emphasised. “Broadway,” she answered, endeavouring to force a new association of ideas to replace one which she strove to conceal.
“Safe.” “Vaults.” Out of the corner of my eye I could see that the indicator showed a tremendously increased heart action. As for the reaction time, I noted that it was growing longer and more significant. Remorselessly he pressed his words home. Mentally I cursed him.
“Rubber.” “Tire.”
“Steel.” “Pittsburg,” she cried at random.
“Strongbox,” No answer.
“Lock.” Again no answer. He hurried his words. I was leaning forward, tense with excitement and sympathy.
“Key.” Silence and a fluttering of the blood pressure indicator.
“Will.”
As the last word was uttered her air of frightened defiance was swept away. With a cry of anguish, she swayed to her feet. “No, no, doctor, you must not, you must not,” she cried with outstretched arms. “Why do you pick out those words of all others? Can it be—” If I had not caught her I believe she would have fainted.
The indicator showed a heart alternately throbbing with feverish excitement and almost stopping with fear. What would Kennedy do next, I wondered, determined to shut him off as soon as I possibly could. From the moment I had seen
