"Bernard L. Majendie and John Slade."
The detective raised his eyebrows in surprise.
"They were there—together?"
"They came separately. Slade joined the party at the last moment; he was not expected."
"A very interesting crowd," said the detective slowly, studying the list. "What servants?"
"None."
"You are sure?"
"Mrs. Kildair has only two, a Japanese butler and a lady's maid, both of whom were out."
"You are positive?"
"Absolutely. The occasion was an informal supper. Mrs. Kildair, while preparing the dishes, placed her three rings on the pin-cushion of her dressing-table—at this point here on the plans—fastening them with a hatpin. The table, as you see, can be easily seen both from the studio and the dining-room."
