“Certainly. It is one of my duties to open the safe every morning, and lock it the last thing at night.”

“Did you find the safe just the same as when you left the night before?”

“Exactly the same. Apparently the lock had not been tampered with.”

“Proceed.”

Clark spoke with a visible effort. “I unlocked the safe and pulled open the door and found—” his voice broke. “At first I could not believe the evidences of my senses. I put out my hand and touched Mrs. Trevor. Then, and then only, did I appreciate that she was dead. In unspeakable horror I ran out of the room to summon aid.”

“What led you to think she was murdered? Doctor Davis did not know it until much later.”

“I beg your pardon. I had no idea Mrs. Trevor was murdered.”

“Then, why did you cry ‘Murder’ as you ran along?”

“I have no recollection of raising such a cry. But I was half out of my senses with the shock, and did not know what I was doing.”

Clark’s handsome face had turned a shade paler, and he moistened his lips nervously. Mrs. Macallister noticed his agitation, and gave vent to her feelings by pinching Peggy’s arm.
