When he had climbed the steps Marston stopped. Now he had started on his adventure he saw its difficulties. To begin with, he must pass two or three vessels, and the lights that burned on the steamer touched the mole. She came from Cadiz and Spanish passenger boats carried a _Sereno_, whose particular duty was to keep watch at night. Marston was afraid the man might hail him. Although he had laboriously studied Castilian, he did not speak it well, and his accent would indicate that he was a foreigner. If the _Sereno_ were curious and kept him talking, the port-guard might come up. Anyhow, there was some risk of his meeting the latter and he would then be asked to account for his wandering about in the dark. It was obvious that he could not do so satisfactorily, and there was a telephone to the Government office at the Capital. Marston doubted if Larrinaga could imprison him for spying, but it did not matter much. If he were found at San Cristobal, Don Ramon would know his object and would not let him go until he had sent off his soldiers to put down the Bat. If the latter were not warned, he would probably be surprised and captured. This was unthinkable, and Marston saw he must not be caught, although to run away from the port-guard might lead to his getting shot. The fellows carried pistols, which they were empowered to use. Caution was plainly needed, and he crept past the steamer, keeping close to the high parapet of the mole. Nobody hailed him, and he went on until he came opposite a small marque. She had no lights, but as he stole by his foot struck a mooring rope and he fell. He lay flat on the ground for some moments, and then, hearing no movement on board, got up and crept away, looking out for the next rope. The mole was long and he had not gone far when he heard the splash of oars. A boat came out of the dark, and a break in the wall indicated a row of steps. Marston did not want to turn back, and it was possible the men were going to one of the vessels. If they were going to the town, he had better get past the steps before they landed. A pile of goods forced him to leave the gloom of the parapet and it looked as if his figure cut against the sky, for the splash of oars stopped. "_Ola compañero!_" somebody shouted. Marston saw he must trust his luck and asked gruffly: "_Que quiere?_" The man said they were coming to let go a schooner's rope but he might throw it down, and Marston dragged the heavy warp to the edge. "_Coje-le_," he said in a hoarse voice and threw down the rope. He imagined it fell upon the others' heads, for somebody said, "_Mal rayo! Esta borracho._" Then the boat pulled away and Marston went on. If the fellows thought him drunk, so much the better. This would account for his brevity and uncouth accent. He wondered whether the shouting had excited the port-guards' curiosity, but although he stopped to listen he heard nothing.
