“Well, let’s get on. What about the gardeners?”

“Two of them were working in a field about a mile from the Maze all afternoon. Each clears the other.”

“And the third gardener who was on the spot that day—the man Skene?”

“His story is that he was working in the kitchen-garden near the house. There’s no evidence against that.”

“The maids? And the chauffeur?”

“All accounted for. They had nothing to do with the affair.”

“And Stenness?”

Wendover looked keenly at Sir Clinton as he brought out the secretary’s name; but the Chief Constable showed no sign of special interest.
