The doctor was utterly nonplused.  He prescribed a quieting potion, and went away, promising to return again in the morning.

“And perhaps you had better humor him in his desire to be left alone,” he said to Mrs. Pell.  “But of course arrange to be near in case another collapse occurs.”

The household separated for bed that night with sober faces.

“Syd hasn’t been like himself since Mr. Tyler died,” remarked Roy, lingering at the door of Rex’s room.

Rex did not reply immediately.  He stood looking at his brother intently for an instant, then he put a hand on Roy’s shoulder, gently pulled him into the room and closed the door behind him.

“Sit down a minute, Roy,” he said gravely; “I want to tell you something.”

“What is it?  What makes you look so solemn, Reggie?  Is it anything about Syd?”

“Yes, it’s about Syd.  Something that happened last summer, and which he told me not to tell; but it seems to me that I ought to tell now.”

In a few words then, Rex related what he and Scott Bowman had witnessed, adding an account of what Sydney had said to him when he asked to have the doctor sent out of the room.

“It’s queer, isn’t it, Roy?” Rex added.

“Yes, but I can’t connect it with the present case.”

“Neither can I. That makes it queerer still.  Perhaps you’d better not say anything about what I told you.”

“No, I shan’t,” and the boys sat quiet a while longer, discussing the mystery of this affair in lowered tones.

Meanwhile Sydney in his room across the hall, was lying in his bed with his eyes wide open staring at the ceiling.  Now and then he passed his hand across his forehead, on which the perspiration kept gathering.

“It is Nemesis,” he murmured over and over.  “I have felt that it would come, and now at last it has appeared, and through Rex, of all the others!”

All through that night he remained thus wakeful.  He watched, helplessly, the gradual breaking of the dawn, knowing that he had not slept a moment and feeling that he must have this physical ill to bear in addition to the mental one which already weighed him down to the earth.

But he had come to the turning point now.  In some way this was a relief, even though the prospect immediately ahead of him was such a fearsome one.

He wished that he could go up to the office without seeing any of the family, as he had done that other morning in Marley.

But he could not do this now.  They would worry and send after him.  He must try and get through the ordeal of facing them as best he could.

He rose at the usual time, but before he had finished dressing there was a knock at the door and Roy’s voice wanting to know how he was.

“All right,” he replied, and then, as his brother asked if he might come in, he opened the door.

“All right!” exclaimed Roy, after one look at his face, “Oh, Syd!”
