Again and again I shouted for help, but could attract no notice. My position was far from secure, compelled to cling on to those iron footholds in the brickwork.

At last I saw a newsboy close to me. My shout startled him, but when he discerned my face beneath the bars he came closer, and asked,—

“’Alloa, guv’nor! What’s up?”

“I’m a prisoner here,” I explained. “Go and fetch a policeman.”

“My gum!” exclaimed the urchin in his surprise. “It’s the first time I’ve ever ’eard of a bloke gettin’ locked down the sewer.” And he went off at once to call a constable.

The officer came quickly, and after a brief explanation he sent the lad somewhere to the house of one of the sewermen, I think, for the key.

Meanwhile, a small crowd quickly collected around the grating, and I was subjected to a good deal of good-humoured banter until the man came with the key, and I once again found myself at the surface, a dirty, dishevelled, pitiable-looking object in evening dress. I was in Oxford Street, at the corner of Hart Street, Bloomsbury.

Both constable and sewer-man were curious to know how I got in, whereupon I explained that I had been the victim of a plot in some house, of the exact situation of which I was unaware.

The two men exchanged glances—meaning glances I saw them to be.

“Was it anywhere near Portland Place?” asked the big fellow in blue jersey and sea-boots.
