"Yes--yes--I know. Bring it in--paper and box and all. Where did you get it?"

Allen explained how Jane Wasp received it from Cain at Colchester, and Mr. Hill listened attentively. "I understand now," he said at length. "Put the things in my study. I'll see you later--say in two hours."

The young man, wondering what it all meant, departed and left his father to take--on the face of it--a much needed sleep. He went outside and picked up the cross, the box, and the paper, which still remained on the grassy bank near the gate. These he brought into the study, and examined them. But nothing was revealed to his intelligence. The box was an ordinary cardboard one; he did not recognise the ill-formed writing, and the cross was simply two sticks tied together by a wisp of dry grass. Why the contents of the box should have terrified his father Allen could not say. And that the sight of the symbol did terrify him, he was well assured, since Mr. Hill was not a man given to fainting. The box came from some one who knew Mr. Hill well, as the name Lawrence was on it, and this was his father's second name rarely used. Mr. Hill usually called himself Harold, and suppressed the Lawrence. But Allen had seen the middle name inscribed in an old book, which had been given by Strode to Hill in their college days. This coincidence made Allen wonder if the sending of the cross and the use of the rarely used name had anything to do with the murder.

While he thus thought, with his face growing darker and darker, the door opened and Mrs. Hill entered. She had been working in her own room, and knew nothing of the affair. But some instinct made her aware that Allen was in the house, and she never failed to be with him when he was at home. Indeed, she was hardly able to bear him out of her sight, and seized every opportunity to be in his presence. With this love it was strange that Mrs. Hill should be content that Allen should remain in South America for so long, and pay only flying visits to the paternal roof.

"You are back, Allen," she said softly, and came forward to lay her hand on his wrinkled forehead. "My dear boy, why that frown? Has Eva been unkind?"

"Oh no," said Allen, taking his mother's hand and kissing it, "she will not marry me yet."

"Foolish girl. What does she intend to do--stop with Mrs. Merry, I suppose, which is a dull life for her? Far better if she came to me, even if she will not marry you at once."

"She has accepted the position of companion to Mrs. Palmer."

"Indeed," said Mrs. Hill, looking surprised; "I should have thought her pride would have prevented her placing herself under an obligation."

Allen shrugged his shoulders. "There is no obligation," he said; "Eva is to be paid a salary. Besides, she likes Mrs. Palmer, and so do I."
