Merrington was obviously startled at this unexpected information.

"This is news to me," he said gravely. "Where did you learn it?"

"From the War Office this morning. There is no possibility of mistake. Nepcote was in London on the night of the murder."

"He probably has an explanation, but what you have just told me is an additional reason for seeing and questioning Nepcote without delay, even if I have to send a man to France for the job."

"It will not be necessary for you to do that. Nepcote returned to London two days ago—sent over on some special mission. I ascertained that fact also from my friend at the War Office."

Merrington glanced at a small clock which stood on the desk in front of him.

"I will go immediately and see him myself," he said.

"I should like to accompany you."

"I shall be delighted to have you," replied Merrington with complete untruth. "I have Nepcote's address included in the list of guests who were at the moat-house at the time of the murder," he added, opening his pocket-book and hastily scanning it. "Ah, here it is—10 Sherryman Street. I'll send for a taxi-cab. Is there anything I can do for you in return for your kindness in bringing me this information?"

"I should be obliged if you would lend me a copy of the coroner's depositions in the Heredith case."
