r in citizen's clothes at once, and despatched
it by him, with the injunction to let very little grass grow under
his feet on the way down to headquarters. He then summoned the
waitress into the library.
"Have you said anything to Margaret about the china?" he asked.
"Yes, sir," she replied.
"What did you say?"
"I told her as how wasn't it funny the way it had went, sir."
"And what did she say?"
"Nothing, sir. Only she seemed to think it was funny, because she
laughed."
"And what did you say then?"
"Nothing, Mr. Perkins. Margaret and me have very little
conversation, because she don't fancy me, and prefers talkin' to
herself like."
"H'm!" said Thaddeus. "Talks to herself, does she?"
"All the time, sir," returned the waitress, "and she seems very fond
of it, sir. She laughs, and says things, and then laughs again.
She does it by the hour."
"How long has this been going on?"
"About a week, sir. I noticed it first last time I had my day out.
I didn't get in until nearly eleven o'clock, and I found her sitting

Thaddeus's brow grew thoughtful again. It wrinkled into a half-
dozen lines as he asked:
"Why didn't you speak of this before?"
"It ain't for me to be telling tales, Mr. Perkins," she said. "All
cooks as I've lived with is queer like, and I didn't think any more
about it."
"All right," said Thaddeus. "You may go. Only, Mary, don't speak
of the plates again to Margaret. Say as little to her as you can,
in fact, about anything. If you notice anything queer, report to me
at once."
The waitress left the room, and Thaddeus turned to his desk. It was
plain from his appearance that light was beginning to be let in on
places that up to this point had been more or less dark to him,
although, as a matter of fact, he could not in any way account for
the mystery of the vanished plates any more than he could for th
