Part 6 (1/2)

Like a flash he was away through the brush. Speed and the utmost caution were necessary. If a limb cracked, if he fell over a hidden ditch, the quarry would be frightened away. He must see what was going on, see it with his own eyes.

Fairly holding his breath, he struggled forward. Now he had covered a third of the distance, now half, now three-quarters and now--

His lips parted in an unuttered groan. He leaped out of the bush.

Something flashed in his hand. For a second that thing was pointed down the road where the speedy car had suddenly resumed its journey. Then his hand dropped to his side.

”No,” he said slowly, ”it won't do. Too risky. Guess they haven't seen me. If not, they will be back. And next time,” he shook his fist at the vanis.h.i.+ng car, ”next time my fair lad or lady, you won't escape me.”

Turning back, he again disappeared into the brush.

In the meantime things were happening in the air. Coles Masters, who was in charge of the secret tower room, had his hands full. He switched on this loud-speaker and lowered that one to a whisper. He tuned in this one and cut that one out.

”Whew!” he exclaimed, mopping his brow, ”what a night! Wish Curlie were here.”

To start the night's entertainment a boy had broken in on the radio concert. Then a crank had come shouting right into the middle of a speech by a politician. A few moments later a message on 1200 had fairly burst his ear-drums. The message had been short, composed of just three words:

”Dark, cloudy night.”

”Regular thunderbolt behind that!” he muttered as he measured the location and found it to come from the city's great hotel. ”Enough there to send it round the world. Shouldn't be surprised to get the echo of it in a few seconds myself. The nerve of the man!”

In strange contrast to this was the whisper which followed within five minutes. It was sent on 200.

”h.e.l.lo, Curlie. Did you get that? Terrible, wasn't it?” came the whisper. ”But, Curlie, I don't think you need to bother about him. He's leaving in a day or two. He's going, far, far away. He's going north; out of your territory entirely. I know you'd love to catch him, Curlie, but it would be dangerous, awfully dangerous! So don't you try, for he is going far, far away.”

Coles Masters' fingers had worked rapidly during this whispered message.

Not only had he measured the distance and taken the location, but he had written down the message word for word.

”Well, I'll be jiggered!” he muttered. ”That was a girl, a young girl and a pretty one too, or I miss my guess. Anyway she has an interesting whisper. She's at that same hotel and seems to know Curlie. She must have broken in on my 1200 friend. So he's going north? Can't go any too soon for me. Mighty queer case. Have to turn it over to Curlie. It's all Greek to me.”

”h.e.l.lo, there! What--”

He wheeled about to snap a b.u.t.ton. A message was being shouted out on 600.

”That's the chap Curlie's after. So he hasn't got him yet? Well, here's hoping he hurries.” His pencil began rapidly writing the message.

Meanwhile Curlie in his woods retreat had moved silently over to the other side of the driveway.

”Probably will come back the other way,” he concluded.

He did not remain behind the fence this time but threw himself into the shallow depths of a dry ravine. He remained keenly alert. His eyes were constantly on the road, which lay like a brown ribbon a full mile straight before him.

He was thinking of his various cases. Equal in interest to the one which he was now hunting down was that big hotel case. He was thinking of the girl. Why had she whispered those messages to him? Was she merely a tool of the man behind the powerful radio machine? Was she simply leading him on? He could not feel that she was. Somehow her whisper had an accent of genuine interest in it.

”Wonder what she's like,” he asked himself. Then, with a smile playing about his lips, he tried to guess.

”Small, very active, has dark brown hair and snappy black eyes.” After a moment's thought he chuckled: ”Probably really a heavy blonde; something like two hundred pounds. You can't tell anything by a voice. You--”

Suddenly he braced himself up on his elbows. His keen ears had caught a distant purring sound. Two yellow b.a.l.l.s of fire were rapidly approaching--the headlights of a fast-moving automobile.
