“Stephen has got him shut up in that tower.”

“Alive?”

“Alive! Go along, Johnny! You don’t suppose he’d keep him there if he were dead. Those cries we heard to-night were human cries; words; and that was a human voice uttering them, as my ears and senses told me; and my brain has been in a muddle ever since, all sleep gone clean out of it. Just now, turning and twisting possibilities about, the solution of the mystery came over me like a flash of lightning. Ste has got Frank shut up in the Torr.”

He, standing there upright by the bed, and I, digging my elbow into the counterpane and resting my cheek on my hand, gazed at one another, the perplexity of our faces showing out strongly in the moonlight.

IV.

Mr. Duffham the surgeon stood making up pills and powders in his surgery at Church Dykely, the mahogany counter before him, the shelves filled with glass bottles of coloured liquids behind him. Weighing out grains of this and that in the small scales that rested beside the large ones, both sets at the end of the counter, was he, and measuring out drops with a critical eye. The day promised to be piping-hot, and his summer house-coat, of slate-coloured twill, was thrown back on his shoulders. Spare and wiry little man though he was, he felt the heat. He was rather wondering that no patients had come in yet, for people knew that this was the time to catch him, before he started on his rounds, and he generally had an influx on Monday morning.

Visitor the first. The surgery-door, standing close to the open front one, was tapped at, and a tall, bony woman entered, dressed in a big straw bonnet with primrose ribbons, a blue cotton gown and cotton shawl. Eunice Gibbon, Mrs. Stephen Radcliffe’s sister.

“Good-morning, Mr. Duffham,” she said, lodging her basket on the counter. “I’m frightfully out o’ sorts, sir, and think I shan’t be right till I’ve took a bottle or two o’ physic.”

“Sit down,” said the doctor, coming in front of the counter, preparatory to inquiring into the symptoms.

She sat down in one of the two chairs: and Duffham, after sundry questions, told her that her liver was out of order. She answered that she could have told him that, for nothing but “liver” was ever the matter with her. He went behind the counter again to make up a bottle of some delectable stuff good for the complaint, and Eunice sat waiting for it, when the surgery-door was pushed open with a whirl and a bang, and Tod and I burst in. To see Eunice Gibbon there, took us aback. It seemed a very curious coincidence, considering what we had come about.
