“Such a day!” she murmured with a sigh. “Have you been able to sleep?”

“I haven’t tried,” I said. “I knew it would be no use.”

“Miss Dotty is still upset,” went on Maida. “And the training nurses are following their own devices, and everybody is afraid of her own shadow. I wish this business was all settled and forgotten about.”

“You don’t wish it any more than I do,” I agreed fervently. “But I do think that O’Leary is doing everything within his power.”

“I suppose so,” said Maida, without much conviction. She was looking pale and rather ill. “Wasn’t that Mr. O’Leary driving away a moment ago?”

“Yes.”

“I didn’t know that he was here at St. Ann’s. He hasn’t seen fit to question me yet”—she smiled rather ruefully—“as to poor Higgins. Except, of course, as he did at the inquest and that was so little. I felt he was reserving his inquiry, didn’t you? But I thought Mr. O’Leary had gone back to town long ago.”

“No. He just left.” I paused to yawn. “I’m going to try to get some sleep. Better do likewise.” But she shook her head, murmuring something about work, and I went to my room.

Luckily I managed to fall into an uneasy sleep. It was when I had awakened that I found I possessed but one remaining clean uniform and it was of a style that demanded the buttons I had sent to the laundry. Recalling the fact that Maida had an extra set, I went to her room to borrow. She was not there but I went boldly into the room.

And I found the radium!
