Hugh dashed the brass inkwell at the head of Doctor Bergius. The doctor collapsed over the table. Castelli, who was still on the floor in a crouching position, clutched at Hugh’s leg. Hugh launched a vicious kick and caught him on the jaw. With one bound, he was behind the crimson curtains, and out on the terrace. He leaped the balustrade and plunged into the shrubbery. Madly he tore on. About fifty yards away was a high wall. He leaped at it desperately. His hands just clutched the coping, and he hung, slipping and scraping, feeling for a foothold. Then his toe caught in a tiny projection, and in another moment he had drawn himself up.

Spat! Spat! went the plaster of the wall.... They were firing at him as they ran. Golaz and Gamba came plunging through the bushes. They were appallingly near. The top of the wall was covered with bits of broken glass that caught his dressing-gown, as he leaped down on the other side. As he tried to wrench it free, a brown hand reached over and gripped it. With a twist and a turn, Hugh wriggled out of it. His pistol fell from the pocket. He snatched it up and rushed on.

A few yards further he darted behind an ancient olive tree and looked back. Gamba was already astride of the wall. Hugh fired twice and he saw the man drop back. Then he ran blindly on, taking the terraces of olive trees in reckless leaps, often landing on his knees. At length he came out on the mountain side amid boulders and prickly scrub. He dodged among the rocks, and cowered behind the bushes. He was torn and bleeding in a dozen places, and his clothes were in shreds. Presently he sank exhausted.

For over an hour he lay without moving. Everything was quiet; they had evidently given up the pursuit. He rose and by a round-about route he made his way back to the Casino.

Bob Bender was waiting for him on the steps. He looked anxious and excited. He dragged Hugh through a side door.

“Quick! tell me what’s happened. You’re in a hell of a state. We were afraid they’d got you.”

“Didn’t you know?... Vulning has escaped.”

“No!”

“Yes, he arrived at an awkward moment for me. I’ve had to jolly well risk my life for your people.”

“Vulning must have got out by the window. It was over thirty feet from the ground. We never thought of guarding that. He must have made a desperate effort.... Well, did you discover anything?”
