“Have you a pair of race-glasses, Joan? Prismatics, or even opera-glasses? Tell Mold where he can get them, please.”

Joan gave the keeper instructions and he left the room.

“Knock when you come back again,” Sir Clinton ordered. “I’m going to lock the door to keep out the inquisitive.”

As soon as the keeper was out of earshot, Sir Clinton turned to Joan.

“This fellow Mold, is he a reliable man? Do you know anything about him, Joan?”

“He’s our head keeper. We’ve always trusted him completely.”

She glanced at Sir Clinton, trying to read the expression on his face.

“You don’t think he’s at the bottom of the business, do you? I never thought of that!”

“I’m only collecting facts at present. All I want to know is whether you know Mold to be reliable.”

“We’ve always found him so.”
