The first drops of rain were falling. The fitful breeze of the early morning had strengthened into a westerly wind. Instinctively Marion's thoughts began to dwell on the prospect of the ride over the border in the face of such a storm as was brewing.
Something moving in the road caught her eye, and switched back her thoughts to the present. Simone's noiseless figure was creeping along in front of the gaol wall. The blood rushed to Marion's face. She had forgotten that arrow. Her eyes went alternately from the sentry's steady movement to the fluttering figure in the road. Suppose he should open the wicket?
The light form glided noiselessly back, and Marion glued her eyes again to the grating of the cell.
As the sentry passed round the corner, Marion bent forward and listened for the sound of the grinding of the file. But not by straining her ears to the utmost could she hear anything save the steady tramp of the soldier. Surely there had been time to file through those two bars! In her impatience she forgot that the prisoner was bound to restrict his efforts to the time the sentry spent at the back of the building.
As she sat motionless, her whole forces divided between watching and listening, there was a movement at her elbow. Simone was there with her hat and gloves. Behind her stood Mistress Keziah, her face grey in the dawn.
The clocks in the town chimed half-past three. Marion started. Half an hour Roger had been filing those bars.
'Had you not better go down to the gate and be ready?' said the old lady.
Marion, pulling on her gloves, shook her head. She crouched down again, no eyes for the others in the room, and was unaware that Simone, at a glance from Mistress Keziah, had quietly stolen away.
Marion felt a cold terror grip her heart. Could some one have entered the cell and seen Roger working--seen the arrow and the silk and the cord?
There was the sentry again, idly walking the south front. It seemed hours before he retraced his steps.
As he turned the corner, Roger's face appeared at the grating. He was ready. First knotting the rope to one of the side bars, he pressed his knee against the stone sill, and pulled with both hands first one bar and then another. Slowly the bars yielded. Roger flung out the rope.
