I went downstairs, as I say, just behind Mellish. St Austin's, you must know, is composed of three blocks of buildings, the senior, the middle, and the junior, joined by cloisters. We left the senior block by the door. To the captious critic this information may seem superfluous, but let me tell him that I have left the block in my time, and entered it, too, though never, it is true, in the company of a master, in other ways. There are windows.

Our procession of two, Mellish leading by a couple of yards, passed through the cloisters, and came to the middle block, where the Masters' Common Room is. I had no particular reason for going to that block, but it was all on my way to the House, and I knew that Mellish hated having his footsteps dogged. That Thucydides paper rankled slightly.

In the middle block, at the top of the building, far from the haunts of men, is the Science Museum, containing—so I have heard, I have never been near the place myself—two stuffed rats, a case of mouldering butterflies, and other objects of acute interest. The room has a staircase all to itself, and this was the reason why, directly I heard shouts proceeding from that staircase, I deduced that they came from the Museum. I am like Sherlock Holmes, I don't mind explaining my methods.

'Help!' shouted the voice. 'Help!'

The voice was Bradshaw's.

Mellish was talking to M. Gerard, the French master, at the moment. He had evidently been telling him of Bradshaw's non-appearance, for at the sound of his voice they both spun round, and stood looking at the staircase like a couple of pointers.

'Help,' cried the voice again.

Mellish and Gerard bounded up the stairs. I had never seen a French master run before. It was a pleasant sight. I followed. As we reached the door of the Museum, which was shut, renewed shouts filtered through it. Mellish gave tongue.

'Bradshaw!'

'Yes, sir,' from within.
