"Why, he'll be made to tell, that's all! It isn't right, and it isn't fair that, if he knows anything and can't find the man himself, he should be allowed to keep it a secret and prevent me from earning the reward. I'll bet I'd soon find the man if I had his information--that is, if he's really got any."

"Don't it strike you, Mr. Dobson," the other asked, "that there is some mystery in connection with Occleve House that he knows of? What with his having the garden locked up, and his always being about there!"

"It did once, but I have thought it over, and I can't see how the house can be connected with it. You see, on that night it so happened there was no one in the house but the footmen and the women servants. His lordship and the valet had gone off to stay at the hotel, and Mr. Smerdon had gone down in the morning to the country seat, so what could the murderer have had to do with that particular house? And it ain't the house the Señor seems to think so much about--it's the garden."

"I can't make that garden business out at all," the other said; "what on earth has the garden got to do with it?"

"That's just what he won't say. But you mark my words, I ain't going to stand it much longer, and he'll have to say. If he don't tell pretty soon what he knows, I shall get the Home Office to make him."

Meanwhile the Señor, who had bewildered Lord Penlyn and Mr. Stuart by the connection which he seemed to feel certain existed between the garden of Occleve House and the murder in the Park, excited their curiosity still more when he suddenly announced one evening that he was going down, with his lordship's permission, to pay a visit to Occleve Chase.

"Certainly," Penlyn replied, "you have my full permission; I shall be glad if you will always avail yourself of anything that is mine. But, Señor Guffanta, you connect my houses strangely with this search you are making--first it was this one, and now it is Occleve Chase----; do you not think you should confide a little more in me?"

"I cannot confide in you yet, Lord Penlyn. And, frankly, I do not know that I have much to confide. Nor am I connecting Occleve Chase with the murder. But I have a wish to see that house. I am fond of old houses, and it was Walter's property once though he never possessed it. I might draw inspiration from a visit to it."

For the first time since he had known the Señor, Lord Penlyn doubted if he was speaking frankly to him. It was useless for Guffanta to pretend that he was not now connecting Occleve Chase in his own mind with the murder, as he had certainly connected the old disused garden previously--but whom did he suspect? For one moment the idea flashed through his mind that perhaps, after all, he still suspected him; but another instant's thought served to banish that idea. Whatever this dark, mysterious man might be working out in his own brain, at least it could not be that. Had he not said that, by some strange chance, he had once stood face to face with the assassin? Having done so, there could be no thought in his mind that he, Penlyn, was that assassin. But, if it was not him whom he suspected, who was it?

"Well," he said, "you must take your own way, Señor Guffanta, and I can only hope it may land you aright. Only, if you would confide more in me, I should be glad."
