Approximately an hour afterwards, Miss Mines reported urgently through the communicator, "They'll reach the lock in less than four minutes now, Dasinger! Better drop it and come up!"

"I'm on my way." Dasinger reluctantly switched off the beam-saw he was working with, fastened it to the belt of the salvage suit, turned in the murky water and started back towards the upper sections of the wreck. The job of getting through the tangled jungle of metal and plastic to the gem vault appeared no more than half completed, and the prospect of being delayed over it until the Spy discovered them here began to look like a disagreeably definite possibility. He clambered and floated hurriedly up through the almost vertical passage he'd cleared, found daylight flooding the lock compartment, the system's yellow sun well above the horizon. Peeling off the salvage suit, he restored the communicator to his wrist and went over to the head of the ramp.

The five men came filing down the last slopes in the morning light, Taunus and Calat in the lead, Graylock behind them, the winged animal riding his shoulder and lifting occasionally into the air to flutter about the group. Quist and Egavine brought up the rear. Dasinger took the gun from his pocket.

"I'll clip my gun to the suit belt when I go back down in the water with the boys," he told the communicator. "If the doctor's turning any tricks over in his mind, that should give him food for thought. I'll relieve Quist of his weapon as he comes in."

"What about the guns in Graylock's hut?" Duomart asked.

"No charge left in them. If I'm reasonably careful, I really don't see what Dr. Egavine can do. He knows he loses his half-interest in the salvage the moment he pulls any illegal stunts."

A minute or two later, he called out, "Hold it there, doctor?"

The group shuffled to a stop near the foot of the ramp, staring up at him.

"Yes, Dasinger?" Dr. Egavine called back, sounding a trifle winded.

"Have Quist come up first and alone, please." Dasinger disarmed the little man at the entrance to the lock, motioned him on to the center of the compartment. The others arrived then in a line, filed past Dasinger and joined Quist.

"You've explained the situation to everybody?" Dasinger asked Egavine. There was an air of tenseness about the little group he didn't like, though tension might be understandable enough under the circumstances.

"Yes," Dr. Egavine said. "They feel entirely willing to assist us, of course." He smiled significantly.

"Fine." Dasinger nodded. "Line them up and let's get going! Taunus first. Get ..."
