He was a long way from home. Home was in the north where he had grown up as the unloved son of a widower lawyer who had sent Salvador to a church school. He had become a priest because he did not know what else he should be, but now he wished he had been a soldier. He thought he would have been a good soldier, but fate had made him a sailor instead. He had been a chaplain on board a Spanish ship captured at Trafalgar and in the darkness above him the sound of battle crashed again. The sound was the boom and snap of the great canvas sheets that protected the cathedral’s half-built dome, but the wind made the huge tarpaulins sound like cannons. The canvas, he knew, had once been the sails of Spain’s battle fleet, but after Trafalgar the sails had been stripped from the few ships that had limped home. Father Salvador Montseny had been in England then. Most Spanish prisoners had been put ashore swiftly, but Montseny was chaplain to an admiral and he had accompanied his master to the damp country house in Hampshire where he had watched the rain fall and the snow cover the pastures, and where he had learned to hate.

And he had also learned patience. He was being patient now. His hat and cloak were soaked through and he was cold, but he did not stir. He just waited. He had a pistol in his belt, but he reckoned the priming powder would be sodden. It did not matter. He had a knife. He touched the hilt, leaned on the wall, saw another wave break at the street’s end, saw the spray dash past the dim light from an unshuttered window, and then heard the footsteps.

A man came running from the Calle Compania. Father Montseny waited, just a dark shadow in dark shadows, and saw the man go to the door opposite. It was unlocked. The man went through and the priest followed fast, pushing the door open as the man tried to close it. “Gracias,” Father Montseny said.

They were in an arched tunnel that led to the courtyard. A lantern flickered from an alcove and the man, seeing that Montseny was a priest, looked relieved. “You live here, Father?” he asked.
