"I think I have seen him. But Koku spoiled everything by trying to eat him up," and Tom laughingly related what had occurred on the way from Shopton.

"Bless my boots!" said Mr. Damon. "You'd better see the police, Tom."

"What for?"

"Why, they ought to know about such a fellow lurking about Shopton. If he followed that Western railroad president here--"

"We'll hope that he will follow Mr. Bartholomew away again," chuckled Tom. "Mr. Bartholomew won't stay over today. When that chap finds he has gone he probably will consider that there is no use in his bothering me any further."

Whether Tom believed this statement or not, he was destined to realize his mistake within a very short time. At least, the fact that he was being spied upon and that the enemy meant him anything but good, seemed proved beyond a doubt that very week.

Having done the little job for Mr. Damon, Tom allowed no other outside matter to take up his attention. He shut himself into his private experimental workshop and laboratory at the works each day. He did not even come out for lunch, letting Rad bring him down some sandwiches and a thermos bottle of cool milk.

"The young boss is milling over something new," the men said, and grinned at each other. They were proud of Tom and faithful to his interests.

Time was when there had been traitors in the works; but unfaithful hands had been weeded out. There was not a man who drew a pay envelope from the Swift Construction Company who would not have done his best to save Tom and his father trouble. Such a thing as a strike, or labor troubles of any kind, was not thought of there.

So Tom knew that whatever he did, or whatever plans he drew, in his private room, he was safely guarded. Yet he always took a portfolio home with him at night, for after dinner he frequently continued his work of the day. Naturally during this first week he did not get far in any problem connected with the proposed electric locomotive. There were, however, rough drafts and certain schedules that had to do with the matter jotted down.

It was almost twelve at night. Tom had sat up in his own room after his father had retired, and after the household was still.

Eradicate was in bed and snoring under the roof, Tom knew. Just where Koku was, it would have been hard to tell. Although a fine and penetrating rain was falling, the giant might be roaming about the waste land surrounding the stockade of the works. The elements had no terrors for him.

Tom locked his portfolio and stepped into his bathroom to wash his hands before retiring. Before he snapped on the electric light over the basin he chanced to glance through the newly set windowpane which had replaced the one Rad had shattered in escaping threatened impalement on Koku's spear.

Although the clouds were thick and the rain was falling, there was a certain humid radiance upon the roof of the porch under the bathroom window. At least, the wet roof glistened so that any moving figure on or beyond it was visible.

"What's that?" muttered Tom, and he sank down lower than the sill and crept slowly to the window. He merely raised himself until his eyes were on a level with the sill.

Coming up over the edge of the porch roof was a bulky figure. It was so dimly outlined at first that Tom could scarcely be sure that it was that of a man.

However, it was not possible that any creature but a man would be able to mount the lattice supporting the honeysuckle vines and so creep out upon the porch roof. Once making secure his footing, the enemy in the dark approached directly the bathroom window at which Tom crouched.

Chapter IX

Where was Koku?

Tom reached up swiftly and pushed over the lever that locked the two window sashes. In doing this he set his own patent burglar alarm. If that lever was turned back again, or broken, the buzzers would be set ringing all over the house, and in Koku's room over the garage.

He did not believe that the marauder on the roof of the porch could have seen the flash of his shirt-sleeved arm. But he took no chance of being observed from outside by rising to his feet.

On his hands and knees he crept away from the window, and out of the bathroom. Once there, he stood up, grabbed the portfolio, and without coat or vest and as he was, dashed out of the bedroom. He had been positive that n.o.body but himself was astir in the big house, and he was right.

He did not punch the light b.u.t.ton when he entered the library. He knew where to put his hand upon an electric torch in the table drawer, and he gained possession of this.

Then he went to the safe and twirled the k.n.o.b and watched the indicator find the four numbers which were the "open sesame" to the burglar and fire-proof door.

He flung the portfolio into the inner compartment, closed both doors, and twirled the combination-k.n.o.b. Then Tom tiptoed to the foot of the front stairs to listen. He could hear no sound from above.

He did not want his father to be startled, if the enemy did break in; and he knew that old Rad, awakened out of a sound sleep, would be worse than useless at such a time.

After all, the giant, Koku, was his main dependence under these circ.u.mstances. Tom crept to the outer door, opened it carefully, and slipped out, letting the spring lock click behind him. For the first time he realized that he was in his shirt and trousers and wore only felt slippers on his feet.

But he was locked out now. He had no key. He must run the risk of the fine rain and the chill of the night air.

He stepped off the end of the porch and ran around the house. It was to the roof of the rear porch that the marauder had climbed. But peer as he might from down in the yard, Tom could see no moving figure up there near the bathroom window. It was pitch dark against the wall of the house.

He turned to glance up at the window of the sleeping room over the garage where Koku was supposed to spend the night. But Tom knew the giant was seldom there during the dark hours. He was as much of a night-prowler as a wildcat or an owl.

There was no light there in any case. But Koku did not use a light much. He could see in the dark, like a wild animal. Tom did not want to call him. If he must have Koku's help, he would have to climb the stairs to his bedside. The giant always aroused as wide awake as at noonday.

But while the young inventor hesitated a sudden, but m.u.f.fled, snap--the breaking of metal--sounded. Tom knew instantly the direction from which the sound came.

Although he could see nothing up there at the bathroom window because of the rain and the deep shadow, he knew that the snapping sound meant the severing of the window lock that he had so recently closed. Some instrument had been forced under the bottom of the lower sash and pressure enough been brought to bear to break the thin steel lever.

On the heels of this sound came another. A m.u.f.fled buzzing somewhere in the house--again! again! And then, startlingly clear from the room over the garage, the burglar alarm went off in Koku's chamber.

"It's all off now!" gasped Tom, and he ran to the foot of the honeysuckle ladder up which he knew the enemy had climbed to get to the roof of the porch. "If he comes down I'll have him!" muttered Tom, staring up into the mist and gloom.

"Fo' de lawsy's sake! 'Tain't mawnin', is it?" Rad's sleepy voice was heard to announce. "No, it's da'k as--" And the voice trailed off into silence.

"Tom! Tom!" the young fellow heard his aroused father shouting.

Tom knew that his father was in no danger. In fact Mr. Swift's voice did not even betray apprehension. It was to the garage Tom looked for an explosion. But none came.

If Koku was up there the prolonged buzzing of the alarm did not awake him. Therefore he could not be there. Tom realized that if the burglar was to be taken the whole affair fell upon his shoulders.

"And I've got my hands full, if it is the fellow with the big feet that we saw on the Waterfield Road the other day," muttered the young inventor.

Nothing stirred on the porch roof. Moment after moment slipped by. Tom began to grow more than amazed. He was worried. What would happen next?

His father had not cried out again. Stepping around to the end of the roofed porch, Tom saw a light in Mr. Swift's room. Rad had evidently gone to sleep again. It would take more than an intermittent buzzer to rouse fully that colored man.

"When old Morpheus has a strangle hold on Rad, Gabriel's trump would scarcely awaken him," Tom muttered.

What had become of the enemy? If it was an ordinary burglar he would have feared the electric alarm instantly. The buzzers were still working. But there was no sign of the man who had set them off at the bathroom window.

Suddenly Tom heard a door slam. It was from the front of the house. Had his father come downstairs to look around and see what the matter was?

The young fellow started around the house on a run. He heard heavy bootsoles spurning the gravel of the path to the front gate. He arrived at the far corner of the house in time to see a man dash through the gateway and run down the street, disappearing finally into the fast-driving rain.

"Fooled me! He went in and right through and down the stairs! Out the front door!" gasped Tom. "Did he get anything? I wonder!"

He sprang up to the front porch and tried the door. It was locked again, of course. Should he ring the bell and get Rad or his father down to the door?
