“But, Liz!” said the tree plaintively.

“I do all the difficult part of the job. All that there was left for you to handle was something a child of three could have done on its ear. And now . . .”

“But, Liz! I’m telling you I couldn’t find the stuff. I was down there all right, but I couldn’t find it.”

“You couldn’t find it!” Miss Peavey pawed restlessly at the soft turf with a shapely shoe. “You’re the sort of dumb Isaac that couldn’t find a bass-drum in a telephone-booth. You didn’t look.”

“I did look. Honest, I did.”

“Well, the stuff was there. I threw it down the moment the lights went out.”

“Somebody must have got there first, and swiped it.”

“Who could have got there first? Everybody was up in the room where I was.

“Am I sure? Am I . . .” The poetess’s voice trailed off. She was staring down the Yew Alley at a couple who had just entered. She hissed a warning in a sharp undertone. “Hsst! Cheese it, Ed. There’s someone coming.”

The two intruders who had caused Miss Peavey to suspend her remarks to her erring lieutenant were of opposite sexes—a tall girl with fair hair, and a taller young man irreproachably clad in white flannels who beamed down at his companion through a single eyeglass. Miss Peavey gazed at them searchingly as they approached. A sudden thought had come to her at the sight of them. Mistrusting Psmith as she had done ever since Mr. Cootes had unmasked him for the impostor that he was, the fact that they were so often together had led her to extend her suspicion to Eve. It might, of course, be nothing but a casual friendship, begun here at the castle; but Miss Peavey had always felt that Eve would bear watching. And now, seeing them together again this morning, it had suddenly come to her that she did not recall having observed Eve among the gathering in the drawing-room last night. True, there had been many people present, but Eve’s appearance was striking, and she was sure that she would have noticed her, if she had been there. And, if she had not been there, why should she not have been on the terrace? Somebody had been on the terrace last night, that was certain. For all her censorious attitude in their recent conversation, Miss Peavey had not really in her heart believed that even a dumb-bell like Eddie Cootes would not have found the necklace if it had been lying under the window on his arrival.
