“Does JT have any engine or screw noises?” Buck asked.
Schultz spoke softly into a microphone. “Do you have anything besides pinging on two-two-eight?
“Affirmative,” said the JT speaker. “I hear distant machinery noise. It just started to come in. I think he’s pinging, too. I can hear the clicks.”
“Okay,” said Schultz. “We’ve got it here, too. Keep on it and report any changes. Get us a turn count as soon as you can hear the screws.”
“Okay,” said the voice.
“Did anyone get the commodore?” Buck asked, without turning his head.
“I’m here, Buck.”
“Put the BQR return on the speaker, Schultz. We may as well all hear it,” said Buck.
The pings transported Richardson backward in time. They were exactly the same as they had been during the war, with but a single difference. The intention behind them was unknown. There was also another noise, a high hum, emanating from the same bearing. “I think we’re beginning to pick up his machinery,” said Schultz. “Pretty soon we may hear his screws.” He spoke into his mike. “Can you hear his propellers yet?” he asked.
There was no answer. Schultz gently replaced the mike in its cradle.
“Turn count, one-two-oh!” said the speaker suddenly. “It’s a single-screw ship!”
Helplessly, the crowd around the sonar shack heard the alien submarine close in and resume its former station. “He’d never get away with that if we weren’t immobilized with a tow,” said Buck angrily. “What does he think he’s doing, anyway?”
There was no answer. After a minute, Buck spoke again. “I don’t like this at all, Commodore. I think we should go to battle stations.”
“I think you should, Buck,” said Rich, steadily. “Does your code have a signal for telling the Cushing to do the same?”
“We can tell Keith that we’re doing it. We never thought of putting anything in the code for telling another skipper how to run his ship.”
“Well, tell him we are. He’ll know what to do.”
“Jerry,” said Buck, “are you out there?”
“Right here, Skipper,” said Jerry Abbott’s voice behind Rich.
“Sound battle stations. Here’s the code book.” He slipped the book out of his pocket and held it behind him. “Use the whistle at minimum gain on the after Gertrude. At least that one’s partly directional because of the baffles. Tell her we’re going to battle stations.”
“Wilco,” said Abbott. Rich took the book from Buck’s hand, passed it behind him, felt it taken from him. In a moment the musical chimes sounded through the general announcing system. It was the first time in sixteen years that Rich had heard them except in drill, and again he felt himself driven backward in time. They ceased, and Rich could hear the whistle slowly and precisely sending the Morse code letters AS. The letters were repeated twice, but they were less audible over the bustle of the crew dashing to their stations.

“I think he’s closing us,” said Schultz from the sonar console, where he had taken over his battle station. “He sounds louder, and the decible meter is reading a little higher.”
“Get another bearing from the Cushing, Jerry, and pass him ours when we get it. Schultz, give me a good solid center-bearing thirty seconds from now.” Buck was waiting the agreed-on interval so that his and Keith’s bearings would be at approximately the same time. “Stand by… Mark!”
“One-four-seven by grid,” said Schultz. Jeff Norton wrote the number on two scraps of paper, handed the first to Deedee Brown at the TDC and the second to Jerry Abbott when he came by for it.
Approximately a minute afterward, Brown returned. “Thirty-two-fifty yards,” he said. “Jerry came in the wardroom while we were plotting it; so I guess he’s checking with the Cushing.”
The darkened sonar room was dominated by the sonar console, in the center of which lay, at a convenient angle for viewing, a circular glass-faced tube dimly backlighted in red. The center of the tube was dark, but greenish-white flashes emanated regularly from the four-o’clock sector, halfway to the edge, and each flash coincided with a reverberating ping which jumped from the three pairs of earphones listening to it and bounced around the metal walls of the tiny compartment. Richardson wondered why Schultz, Norton and Buck Williams were not deafened by the piercing, high-frequency echo-ranging signals sent by the other submarine.
He had to tap urgently on Buck’s shoulder to get his attention. “We may as well go active ourselves. He’s not being very polite, and there’s no point in our being polite either. I’ll tell Keith to do the same. Go on short scale at full gain, and aim it right into his receiver, but wait one minute before you start so Keith can go off with you. Does your code cover this?”
“Not all that, Skipper.”
“All right, I’ll tell him on Gertrude.” Grim-faced, inwardly seething and at the same time worried, Rich walked the few steps to the periscope station, vaulted to the elevated platform, picked up the UQC microphone. “Keith,” he said without preliminaries, “this is Rich. We’re going active, and I want you to do the same. Short scale at full gain; aim it right at him. He’s closing in on us. Maybe this will make him be a little more circumspect.”
“Wilco, boss,” said Keith’s voice. “Do you want to start right now?”
“In fifteen seconds. Ping for exactly one minute, then stop. We’ll do the same.”
“Roger!”
Back at the sonar shack, Rich was gratified to see by the sonar console that both submarines blasted forth their beams of concentrated sonar energy at nearly the same instant. The spot on the scope occupied by the stranger was bathed in a rapid succession of flashing pings, and the corresponding echoes were loud and precise. The intruder, as seen on the scope, seemed to have an unearthly, eerie glow, and Rich could have sworn that he could discern, for an instant, the actual shape of the underwater craft.
Schultz positioned the range marker over the spot, read the range. “Thirty-two hundred yards, right on,” he said. “He’s still closing us … no, now I think he’s stopped closing. The range is opening slightly. It’s stabilized on thirty-two hundred.”
Williams gave a coarse laugh. “That barrage slowed him down a little!”
“Maybe, Buck,” said Rich, with the same grim look on his face, “but I wouldn’t bet on anything permanent. My main idea was to show him that he’s fooling around with a couple of United States men-of-war. If he’s a Soviet Navy skipper, that will mean something to him.”
Suddenly, all echo-ranging ceased. There was nothing on the screen. “He stopped too, sir!” said Schultz in a surprised tone. Then he grunted vindictively. “I’ll just bet you there’s a couple pairs of stinging ears over on that sub. They probably had their gain way up, the same as we do when there’s nobody pinging on us. Serves the bastards bloody well right, too. I hope their eardrums are busted good!”
Rich and Buck were again in their somewhat sequestered corner of the sonar compartment. “Skipper,” Buck said in a low tone, “have you any guess at all why he went away and then came back the way he did?”
“I’ve been thinking about the same thing, and the only idea I’ve come up with is that he shoved off to ask for instructions. How long was he gone? You must have it in the sonar log and the quartermaster’s notebook.”
“I already had Jeff look it up. It was five hours forty-three minutes from when we heard him turn away until we heard his echo-ranging when he came back.”
“Then I’d have to guess that he went somewhere within about a two-hour run, got his orders quickly and tore back looking for us. In the meantime, we covered about twenty miles, though it might not have been directly away from his base, whatever that was.”
