full force of his charge. The man doubled up painfully, dropping his weapon to the floor. Aram rolled to his feet, catlike. The Green roared with rage and lunged at him. Aram stepped under the attack and brought his two clenched fists down on the back of the man's neck. The Green staggered and spun about, catching Aram in a vise-like embrace. The policeman was huge, and as his arms closed about Aram's lighter frame, Aram could feel his ribs being crushed. His hand closed on the scalpel he had thrust into the waistband of his shorts. He raised it high and drove it hard into the man's broad back. The Green stiffened. With an incredulous expression, he released Aram and toppled to the stone floor.

The others, they told him, had been killed or captured by the Greens, and one of them must have been forced to tell of the spaceships and the plan of escape through the locks. The steelite doors of the pit were closed, and the remnants of the Group straggled aboard the Star Cluster. Kant Mikal took immediate command of the ship and made ready for the perilous passage through the locks to the sea above. He laid a hand on Aram's shoulder and spoke with feeling. "This isn't the way I planned
