Ashton-Kirk, Investigator Part 29

"To be sure. I have heard something of your teaching staff. It is a very excellent one, is it not?"

"The best in the world." The soft, fat, white hands of the doctor again unclasped themselves; and this time both of them were employed in a faintly traced gesture. "We employ scientists. We do not stop at what you have correctly called the threshold. We explore the entire structure of the intellect. Our Professor Locke, himself an afflicted one, is a man of vast erudition--a scholar of an advanced type, a philosopher whose adventures into the field of psychology and natural science is widely known. He has charge of the practical work of the Mercer Inst.i.tute, and under him its results are positive and unique."

"We have heard of Professor Locke," and, drily, "have seen some of his work."

"If you had stated your business before--ah--coming in to me," spoke the doctor, "you might have had an opportunity of consulting him. He left for his cottage immediately after dining."

"He does not live here, then?"

"Not in this building--no. There is a detached cottage at the far end of the grounds which he occupies. If you'd like to see him," and the heavy jowls of the speaker trembled with eagerness, "Haines will show you there at once."

"If it is no trouble," said Ashton-Kirk, smoothly.

"Not in the least." The doctor rang for his man, and when he entered, said: "These gentlemen would like to speak to Professor Locke. Show them the way to his house. And, gentlemen," to the callers, with anxiety, "the professor can arrange everything with you. It is my habit to nod for a half hour after dinner. My system has grown to expect it, and if I am deprived of it, I suffer considerably in consequence."

"We will not trouble you again, doctor," Ashton-Kirk a.s.sured him.

"Thank you, and good-night."

Once more outside, the man led them along a foot-path that seemed to cut the inst.i.tution grounds in two. The rays of his lantern danced along the carefully kept lawn; the shadowy trees seemed to move backward and forward, as the thin beams wavered among them.

"The professor lives a good piece away," the man informed them. "Away over on the county road."

"Prefers to be alone, eh?"

"I suppose so, sir. And then he has his laboratory and work-shop there, well away from interruption. He don't like to be much disturbed while he is engaged in his studies."

"Few of us do," said Pendleton.

"Quite right, sir."

They walked along in silence for a time; then they caught a clear humming noise from some distance ahead.

"A motor car," said Pendleton.

"It's on the county road," said the man with the light. "We always hear them when the wind blows from that direction."

After some fifteen minutes' steady walking they saw a long twinkling shaft of light coming from among the trees.

"That's the house," said Haines. "I hope the professor ain't busy; you wouldn't believe what a blowing up he can give a body with his fingers when he's vexed. I'd almost rather have the doctor himself; though, as a rule, the professor is a very nice gentleman."

The house was a brick structure of two stories and dimly lighted on the lower floor. Near by was a long, shed-like building, the windows of which were brilliantly lighted.

"He's at work," said Haines, in a troubled tone. "And in the shop too!

If it was even the laboratory, it wouldn't be so bad. But he _does_ get so interested in the shop. That machine means more to him, whatever it is, than anything else about the place."

There came a harsh burring sound from within both the shop and the house. Haines seemed surprised.

"Visitors," he said. "He seldom has one; and I never knew any to come at night before."

They saw the figure of Locke cross one of the shed windows toward a door. And just then Ashton-Kirk stumbled rather heavily against Haines; the lantern dropped to the ground and was extinguished.

"I beg your pardon," said the investigator in a rueful tone; then he began to rub his s.h.i.+ns. "That was rather hard, whatever it was."

The door of the building opened and Locke appeared; his great bald head shone in the light that streamed after him; and it was thrust forward as he strove to penetrate the darkness ahead.

"He feels the vibrations of those buzzers," Haines told them, "and knows right away when anyone wants to get in."

He began fumbling with the lantern as Locke disappeared; but Ashton-Kirk said to him:

"You need not light that. We can see very well. And, on second thought, you need not wait, either. We can introduce ourselves to Professor Locke without troubling you further."

"Thank you, sir," said the man, vastly relieved. "They all have queer dispositions, you see, and I don't like to trouble them."

At once Haines made his way back along the path by which they had approached; some distance away they saw him kindle his lantern, and then watched the yellow spark as it glanced fitfully away across the grounds.

The cottage and work-shop of Professor Locke appeared to be set back some little distance from what Haines had called the county road; a grove of tall trees thickened the shadows all about, and it was into these trees that the professor had gone.

"The buzzer must have the b.u.t.ton that sounds it attached to a gate opening upon the road," said Pendleton.

They stood for a short time in silence; then Pendleton nudged his friend with an elbow.

"Look," he whispered. "There at the door of the shed."

Ashton-Kirk did so. And he was just in time to see a large, iron-gray head, a craggy, powerful face, and a pair of thick shoulders; the expression and att.i.tude were those of a man listening intently. Almost instantly, as Ashton-Kirk's gaze fell upon him, the man withdrew.

"Humph," exclaimed Pendleton under his breath. "Who's that, I wonder?"

They waited for some time longer in silence. But the little man did not return, nor did the head appear again at the shop door.

Ashton-Kirk appeared puzzled.

"Locke intended returning at once," he said to Pendleton. "Otherwise he would have closed his work-shop door." Then his eyes wandered toward the house, and his grip closed tightly upon his companion's arm. "Look," whispered he, in his turn.

Pendleton's gaze flew toward the house. The lower windows had been dimly lighted when they approached; but now the glow from them was high and brilliant. In one of the rooms they saw Locke; he was striding up and down, his hands clinched and gesturing, his face upturned, writhing hideously. Seated at a table, calmly engaged in examining something traced upon a sheet of paper, and apparently not paying the slightest attention to the gesticulating man, was a young woman. And Pendleton felt himself grow suddenly faint and sick as he recognized Edyth Vale.

CHAPTER XV

MISS VALE DEPARTS SUDDENLY

For a moment there was a silence between the two men; then Ashton-Kirk said, dryly:

"Miss Vale has, apparently, not been altogether frank with us in this matter."

"You think then--" began Pendleton in a voice of terror. But Ashton-Kirk stopped him.

"I think many things," said he. "But they are neither here nor there.
