"A terrible situation," murmured Prelice, looking round again for Jadby, and then saw to his surprise that the man had disappeared. It was apparent that the captain, not liking to be in the same room with the barrister who had thrashed him, had gone out again. However, this was just as well, as Jadby could not listen. "So you removed the knife," said Prelice, eying his friend.
"Yes! It seemed the most reasonable thing to do. I took it away at once, seeing that I could not rouse her for an explanation. It was my intention to hide the knife in my bedroom, and then return to take Mona away. I ran upstairs with the knife, and concealed it in my mattress, and then cautiously came back to the library. When I reached the door, however, I heard someone moving in the room, so thought it best to go back. Don't think me a coward, Dorry. You must see that I was in as dangerous a position as Mona herself, after I hid the knife."
"I quite understand," replied Prelice swiftly. "I expect Captain Jadby was in the library."
"He was. I am certain he was, for just as I reached the first landing I heard the library bell ring. Remember that he said he rang it as soon as he found Mona insensible and Sir Oliver dead."
"What have you done with the knife?"
"It is concealed in my desk in my study in my flat. I dare not produce it, lest I should get into trouble. Besides, its production would do Mona harm, as would my evidence of finding it in her hand. I must hold my tongue, Dorry, and lie as best I am able. But now you can see how needful it was for me to hold my tongue and have you beside me. You must be silent and stand by me."
Prelice shook hands, and they rose to return to the Court. The action brought them round to face the door, and there—at the marble-topped table—they saw Jadby sipping coffee, as though he had never moved. "H'm!" said Prelice, rather puzzled. "The fellow comes and goes like a ghost. Just like a half-caste cat." And he stealthily glanced at the captain, who was ostentatiously reading a newspaper, and took no notice, even when the young men brushed past him to leave the restaurant.
"I say, Ned," remarked Prelice thoughtfully when they were outside, "do you think that Miss Chent will be proved guilty?"
"No. I suppress my evidence about the knife, remember; and then the destroyed will is in her favour. The sole chance for the prosecution to prove Mona's guilt is to find Steve Agstone. He declares that he was looking through the window, and saw Mona kill Sir Oliver."
"To whom did he say this?"
