No-one paid any attention to the working man with his hat pulled down over his eyes and his cape up to his ears. There were hundreds, thousands of men like him, making their way across London for their suppers. John knew the way to Lord Monteagle’s house and slipped from shadow to shadow, making little sound on the dirt and mud of the streets.

Lord Monteagle’s house was lit by double burning torches in the sconces outside. The front door stood wide open and his men, hangers-on, friends, and beggars passed in and out without challenge. His lordship was dining at the top table at the head of the hall, there was a continual press of people all around him, friends of his household, servants, retainers and, towards the back of the hall, supplicants and common people who had come in for the amusement of watching the lord at his dinner. John hung back and surveyed the scene.

As he waited and watched, a man touched his shoulder and went to hurry past him. John recognised one of Lord Monteagle’s servants, a man called Thomas, hurrying to dinner.

The note was in John’s hand, the direction clear. ‘A moment,’ he said, and pressed it into the man’s hand. ‘For your master. For the love of Mary.’

He knew what a potent spell that name would weave. The man took it and glanced at him, but John was already turning away and diving into an alley out of sight. He took a moment and then peered cautiously out.

Thomas Ward had entered the big double doors and was making his way to the head of the table. John saw him lean to whisper in his master’s ear and hand him the note. The job was done. John stepped out into the street again and strolled onward, careful not to hurry, resisting the temptation to run. He strolled as if he were a working man on his way to an inn, hungry for his supper. As he turned the corner and there was no shout of alarm, and no running footsteps behind him, he allowed his pace to quicken – as fast as a man who knows that he should be home by a certain time. One more corner and John allowed himself to run, a gentle jogging run, as a man might do when he was late for an appointment and hoping to make up for the delay. He kept a sharp watch out among the dirt and cobblestones so that he did not slip and fall, and he kept a brisk pace until he was ten, fifteen minutes away from Lord Monteagle’s, out of breath, but safe.
