Presently Mr. Jardine's glance fell on the half-open door of the bath-room. It was a slip of a room cut off the study, a room that had been created within the last twenty years. It was the only room which Mr. Jardine had not inspected before he went down to breakfast.

He pushed open the door, and went in, followed by Towler, wiping the egginess and haminess from his mouth as he went.

'You kept your eye upon this room as well as the others, I suppose,' said
Mr. Jardine, looking about him.

'Yes, sir, I have kept an eye upon everything.'

The apartment was not extensive. A large copper bath with a ponderous mahogany case, panelled, moulded, bevelled, the elaborate workmanship of local cabinet-makers; a row of brass hooks hung with bath towels, which looked like surplices pendent in a vestry; a washstand in a corner, a dressing-table and glass, with its belongings, in the window, and a wicker arm-chair, comprised the whole extent of furniture. No hiding-place here, one would suppose.

Mr. Jardine looked about the room thoughtfully. It was the one apartment in which the patient could hardly be intruded upon by his attendant. Here he could be sure of privacy.

'Did you examine the case of the bath,' he inquired presently, his mathematical eye quick to take in the difference between the inner shell of copper and the outer husk of mahogany.

'No, sir,' answered Towler, briskly. 'Is it 'oller?'

'Of course it's hollow. Surely your eye tells you that.'

'Yes, sir; but there's the hot-water pipes inside—and there's no getting at it, except for a plumber.'
