Unmoving, the prisoner watched them through the grille. Mayhew did not sense any triumphalism in his body language, no sign that he was assured of his freedom, merely a faint curiosity at the change to the pattern that had dominated his life for so many years.

"Sit down!" Osborne bellowed.

"Leave him," Mayhew responded as calmly as he could manage. "We have a more pressing matter."

Above their heads, the distant clamour of battle was punctuated by a muffled boom that shook the heavy door and brought a shower of dust from the cracks in the stone. Silence followed, accompanied by the cloying scent of honeysuckle growing stronger by the moment.

Drawing their swords, Mayhew and Osborne focused their attention on the door.

A random scream, becoming a sound like the wind through the trees on a lonely moor. More noises, fragments of events that painted no comprehensive picture.

Breath tight in their chests, knuckles aching from gripping their swords, Mayhew and Osborne waited.

Something bouncing down the stone steps, coming to rest against the door with a thud.

A soft tread, then gone like a whisper in the night, followed by a long silence that felt like it would never end.

Finally the unbearable quiet was broken by a rough grating as the top bolt drew back of its own accord. His eyes frozen wide, Osborne watched its inexorable progress.

As soon as the bolt had clicked open, the one at the foot of the door followed, and when that had been drawn the great tumblers of the iron lock turned until they fell into place with a shattering clack.

"I… I think I can hear the music now, Mayhew, and there are voices in it," Osborne said. He began to recite the Lord's Prayer quietly.

The door creaked open a notch and then stopped. Light flickered through the gap, not torchlight or candlelight, but with some troubling quality that Mayhew could not identify, but which reminded him of moonlight on the Downs. The music was louder now, and he too could hear the voices.
