must be to assure ourselves that we are right in this
conjecture. I may be entirely wrong, for the unexpected is what I have
been taught to look for in every case of mystery that has come under my
observation. But I believe I have the material at hand to prove the
personality of this Eliza Parsons, and after that I shall know what to
do. Who employs your servants, Mr. Forbes?"

"Martha, my housekeeper, usually employs the maids."

"Will you send for her, please?"

Kenneth at once obeyed the request, and presently Martha entered the
library.

She was a little, withered old woman, but with a pleasant face and
shrewd but kindly eyes.

"Martha," said Kenneth, "did you employ the new linen maid, Eliza
Parsons?"

"Yes, sir," she replied, apparently surprised at the question.

"This is Mr. Burke, Martha. Please answer any questions he may ask you."

"Would you like to see Eliza?" asked Kenneth, when the housekeeper had
retired.

"Not at present. I want to interview Mrs. Hopkins first."

"Tonight?" asked Tom, eagerly.

"I will go at once, with Mr. Forbes's permission."

"Certainly, sir," said Kenneth. "Shall we see you tomorrow?"

"Just as soon as I have accomplished anything."

"Would you like a horse or an automobile?"

"Your man may drive me to the town, sir, if it is convenient."

Kenneth gave the required order, and then Mr. Burke asked:

"How far are you prepared to go in this matter, sir?"

"In what way?"

"In expending money."

"Will any large expenditure be required?"

"I cannot say. But we may require the services and advice of an expert
physician--a s
