A brother went to the cell of Abba Arsenius at Scete and, looking through the window, saw the elder as though he were all fire, for the brother was worthy to see [this.]
When he knocked, the elder came out and saw the brother looking astounded. “Have you been knocking for long?” he said to him.
“You didn’t see anything here?”
but he said: “No.”
The elder conversed with him and sent him on his way.

He looked over his shoulder, like a thief entering a strong room, and his voice sank low.

The Angel of Death came to David's room, He said, "Friend, it's time to go."

She went back into the room and carefully locked the door to the balcony, as if she could lock out all the evil events of the night. ("The End")

"Just why it should have happened, or why it should have happened just when it did, he could not, of course, possibly have said; nor perhaps could it even have occurred to him to ask. The thing was above all a secret, something to be preciously concealed from Mother and Father; and to that very fact it owed an enormous part of its deliciousness. It was like a peculiarly beautiful trinket to be carried unmentioned in one's trouser-pocket - a rare stamp, an old coin, a few tiny gold links found trodden out of shape on the path in the park, a pebble of carnelian, a sea shell distinguishable from all others by an unusual spot or stripe-and, as if it were anyone of these, he carried around with him everywhere a warm and persistent and increasingly beautiful sense of possession.

The tomato hit Brother Leon on his left cheek, a ripe tomato that exploded in juicy fury, splattering his shirt and his hair and smearing his face with what looked like blood. Nobody said anything. Nobody moved. Nobody cheered or booed. Everybody sat there in a profound silence as Brother Leon, mouth agape, wiped the tomato from his face, still silent as he stalked from the stage, leaving an assembly hall full of students who sat stunned, silent for a few minutes, then quietly filed out of the hall. Brother Leon never learned the culprit's name. He, in fact, never made an effort to do so. Nobody else ever mentioned the incident. But Henry Malloran was elected president of the senior class at the next day's election and nobody ran against him.

The dead man and the living man exchanged a long look. Then the youth cautiously put one hand behind him and brought it against a tree. Leaning upon this he retreated, step by step, with his face still toward the thing. He feared that if he turned his back the body might spring up and stealthily pursue him.

Leaning with his back against the door, he could hear this voice, then that one. All was silent but for one voice at a time telling a life. (p214)

Silence thronged the room, and he was aware of the focused scrutiny of the three people who confronted him.

When a man turns a blessing from his door, it falls to them as take it in.

What will you find behind the door that is one door away from Heaven? […] If your heart is closed, then you will find behind that door nothing to light your way. But if your heart is open, you will find behind that door people who, like you, are searching, and you will find the right door together with them.

"What do you think of this, Holmes? Sholto was, on his own confession, with his brother last night. The brother died in a fit, on which Sholto walked off with the treasure? How's that?"
