“Well, I can’t exactly say that it does,” he answered at last, “still, I think the faults I have found can be remedied with a little patience. On the other hand, I fear the improvement I have put in this car may not be as great as I thought when I was working at it.”

Lord Stranleigh looked at the young man with evident approval; his frankness and honesty commended themselves to him.

“Do you mind showing me your improvement and explaining its function?”

“Not at all. You will remember, however, that this exhibition is confidential, for I have not yet patented the mechanism.”

“I shall not mention to anyone what you show me. You asked me a moment ago if I wished to buy an automobile, and I said I did not. I have made a little money in my time, but mostly, it seems to me, by flukes. I do not pretend to be a business man, yet such is the conceit of humanity that I wish to invest some of my money to back my own judgment. If I lose the cash, it won’t cripple me to any appreciable extent. On the other hand, should the investment prove satisfactory, I shall have more faith in my judgment than has hitherto been the case. In any event, I promise to assist you in the formation of your company.”

“That’s all right!” cried the young engineer, with enthusiasm. “My own judgment of men is frequently at fault, but somehow I’d stake my bottom dollar on you. Come over to the window, and I’ll show you how the wheels go round.”

The two men approached the car in the window, and as they did so a third person on the pavement outside stopped suddenly, and regarded them with evident astonishment. Neither of those inside saw him, but if one or the other had looked through the glass, he would have recognised the sinister face of Wentworth Parkes who, having satisfied himself as to the visitor’s identity, turned away and retraced his steps.

Sterling lifted up a leather curtain which hung down in front from the passenger’s seat and disclosed a line of three upright pegs, rising two or three inches from the floor of the car. They were concealed when the curtain was lowered.

“If you give the matter any thought,” said Sterling, “you will discover that the passenger in an automobile is in rather a helpless position. His chauffeur may faint, or even die at his wheel from heart failure, as has been the case in several instances I know of, or he may be drunk, and therefore unreasonable or obstinate, driving the car with danger to all concerned, yet if his master attempt to displace him while the car is going at high speed, disaster is certain. Now, the centre peg here will stop the engine and put on the brakes. A pressure by the foot on the right-hand peg turns the car to the right; and on the left-hand to the left. In the ordinary car the passenger can do nothing to save himself, but here he may stop the car dead, or, if he prefers it, may disconnect the steering wheel, and guide the car at his will.”
