The difficulty was for the observer himself to escape observation. The road was so quiet that if he strolled up and down, those other saunterers in the garden could not fail to have their attention attracted to him sooner or later. It was so narrow that they had only to look up in order to see him leaning against the paling of the opposite house. This house, however, was unoccupied, and behind the paling, in the segment of a circle formed by the shortest of suburban carriage drives, grew a clump of laurels which tempted Harry to do a very foolish thing. He crept into the garden of the unoccupied house, and from a point of vantage among the laurels he watched the two men in the garden over the way. Up and down they walked, backward and forward, and their low voices never ceased; backward and forward, up and down; and now the light of a lamp made oval flames of Lowndes's glasses, now the taller Scrafton's cormorant profile was stamped for an instant on the lighted blinds, while the loathsome sound of his snuff-taking came again and again across the quiet road. So these men were friends: and Lowndes had carefully implied that they were not even acquainted. Why should he have gone out of his way to do that? He had flown into a temper when that careful implication was inadvertently ignored; and had afterwards so feared the tell-tale effect of this unguarded outbreak that he had gone all the way to Teddington with elaborate apologies and ingenious explanations. Stay: no: he had gone to Teddington with an ulterior motive, which only this instant dawned upon Harry Ringrose. Now he thought of it, there had been an obvious absence of premeditation about both the apology and the explanation; in fact, he had never before heard the fluent Lowndes hesitate so often for a word. Why? Because he had gone to Teddington that morning with quite another object, and at last Harry saw what it was. He remembered Mrs. Bickersteth's announcement that this term Mr. Scrafton was coming half-an-hour earlier than formerly. He remembered how cleverly Lowndes had contrived to discover that Scrafton was already in the house. He had never forgotten Scrafton's face on hearing the new master's name. The thing was plain as daylight, and Harry only wondered how and why he had not seen it at once. Gordon Lowndes had gone to Teddington simply and solely to intercept his friend Scrafton, and to warn him that he was about to meet a son of the missing Henry Ringrose.
