"This afternoon? Yes, why were you there? What were you doing?"
"I was interviewing the collector of rents and trying to dig his employer's name out of him. It was Smith's idea. Smith's theory was that the owner of the tenements must have some special private reason for lying low, and that he would employ some special fellow, whom he could trust, as a rent-collector. And I'm pretty certain he was right. I cornered the collector, a little, rabbit-faced man named Gooch, and I believe he was on the point of—What's the matter?"
Betty's forehead was wrinkled. Her eyes wore a far-away expression.
"I'm trying to remember something. I seem to know the name, Gooch. And I seem to associate it with a little, rabbit-faced man. And—quick, tell me some more about him. He's just hovering about on the edge of my memory. Quick! Push him in!"
John threw his mind back to the interview in the dark passage, trying to reconstruct it.
"He's small," he said slowly. "His eyes protrude—so do his teeth—He—he—yes, I remember now—he has a curious red mark—"
"On his right cheek," said Betty triumphantly.
"By Jove!" cried John. "You've got him?"
"I remember him perfectly. He was—" She stopped with a little gasp.
"Yes?"
"John, he was one of my stepfather's secretaries," she said.
They looked at each other in silence.
"It can't be," said John at length.
"It can. It is. He must be. He has scores of interests everywhere. He prides himself on it. It's the most natural thing."
John shook his head doubtfully.
"But why all the fuss? Your stepfather isn't the man to mind public opinion—"
"But don't you see? It's as Mr. Smith said. The private reason. It's as clear as daylight. Naturally he would do anything rather than be found out. Don't you see? Because of Mrs. Oakley."
"Because of Mrs. Oakley?"
"You don't know her as I do. She is a curious mixture. She's double-natured. You called her the philanthropist just now. Well, she would be one, if—if she could bear to part with money. Yes, I know it sounds ridiculous. But it's so. She is mean about money, but she honestly hates to hear of anybody treating poor people badly. If my stepfather were really the owner of those tenements, and she should find it out, she would have nothing more to do with him. It's true. I know her."
The smile passed away from John's face.
"By George!" he said. "It certainly begins to hang together."
"I know I'm right."
"I think you are."
He sat meditating for a moment.
"Well?" he said at last.
"What do you mean?"
"I mean, what are we to do? Do we go on with this?"
"Go on with it? I don't understand."
"I mean—well, it has become rather a family matter, you see. Do you feel as—warlike against Mr. Scobell as you did against an unknown lessee?"
Betty's eyes sparkled.
"I don't think I should feel any different if—if it was you," she said. "I've been spending days and days in those houses, John dear, and I've seen such utter squalor and misery, where there needn't be any at all if only the owner would do his duty, and—and—"
She stopped. Her eyes were misty.
"Thumbs down, in fact," said John, nodding. "I'm with you."
As he spoke, two men came down the broad staircase into the grill-room. Betty's back was towards them, but John saw them, and stared.
"What are you looking at?" asked Betty.
"Will you count ten before looking round?"
"What is it?"
"Your stepfather has just come in."
"What!"
"He's sitting at the other side of the room, directly behind you. Count ten!"
But Betty had twisted round in her chair.
"Where? Where?"
"Just where you're looking. Don't let him see you."
"I don't— Oh!"
"Got him?"
He leaned back in his chair.
"The plot thickens, eh?" he said. "What is Mr. Scobell doing in New York, I wonder, if he has not come to keep an eye on his interests?"
Betty had whipped round again. Her face was white with excitement.
"It's true," she whispered. "I was right. Do you see who that is with him? The man?"
"Do you know him? He's a stranger to me."
"It's Mr. Parker," said Betty.
John drew in his breath sharply.
"Are you sure?"
"Positive."
John laughed quietly. He thought for a moment, then beckoned to the hovering waiter.
"What are you going to do?" asked Betty.
"Bring me a small lemon," said John.
"Lemon squash, sir?"
"Not a lemon squash. A plain lemon. The fruit of that name. The common or garden citron, which is sharp to the taste and not pleasant to have handed to one. Also a piece of note paper, a little tissue paper, and an envelope.
"What are you going to do?" asked Betty again.
John beamed.
"Did you ever read the Sherlock Holmes story entitled 'The Five Orange Pips'? Well, when a man in that story received a mysterious envelope containing five orange pips, it was a sign that he was due to get his. It was all over, as far as he was concerned, except 'phoning for the undertaker. I propose to treat Mr. Scobell better than that. He shall have a whole lemon."
