He eyed the other as he passed, as if he wondered who he was, yet was conscious of no legitimate reason why he should stop him to inquire.

The man drew in the morning air between his teeth, as if he desired to inflate his lungs to the full.

'That was a squeak. It wasn't him I nosed. Who'd have thought that he was there. If he'd come round the corner a minute or two ago there'd have probably been fun. Lucky I emptied the bag before I came on him. Hollo! He's going into Victoria Street. If he uses his eyes he'll spot my bloke in half a minute from now. I'd better put the steam on.'

He quickened his pace, not breaking into a run, for he was aware that nothing arouses attention more than the sight of a man running at that hour in a London street. But for the next ten minutes he moved at a good five miles an hour, going fair toe-and-heel. Then he slackened, judging that for the present he was safe; and, moreover, he was blown.

By what at least seemed devious ways he steered for Chelsea, to find himself, at last, in the King's Road. Thence he made for the river side, pausing before a house which faced the Thames. The house was an old one. In front was a piece of ground which was half yard, half garden. The approach to this was guarded by an iron railing and a gate. The gate was locked. By it was a rusty bell handle. At this he tugged. Almost immediately a window on the first floor was opened about three inches. A voice was heard.

'Who's there?'

'It's me, the Flyman.'

'You've been a devil of a time.'

'Couldn't be no quicker.'

The window was shut again. Presently the front door was opened instead. A man came out. It was Horace Burton. He sauntered to the gate.
