“I think perhaps it would be as well if all of us went in together. It’s quite safe; I’m pretty sure of that. And there’s something there, I suspect, that I shall want witnesses for.”

He summoned Ardsley and Stenness and explained the state of affairs to them.

“If we dowse the sulphur, the wind will clear away the fumes fairly soon. We can get water from the river and put it out. There’s sure to be something in the boat-house which we can use for bringing water—a bucket or a bailer of some sort!”

When it seemed safe, they entered the Maze and soon reached Helen’s Bower. No danger awaited them. Ernest’s body lay sprawling on the grass with a bullet wound in the head and the automatic pistol still clutched in the hand. Sir Clinton crossed over and knelt down beside the corpse.

“We’d better search the body now and be done with it,” he said, beginning the task as he spoke.

“Here’s something bulky in the breast-pocket,” he explained as he extracted it. “H’m! An envelope with your name written on it, Stenness. Your property, perhaps?”

Stenness glanced at the paper and a look of intelligence passed between him and Sir Clinton.

“That’s mine,” he confirmed. “It ought to have notes in it!”

The Chief Constable thrust his fingers into the envelope and, pulling out some of the contents, exhibited them to the company.

“It’s full of notes—must be a fair sum. I’ll keep this for the present, Stenness. You don’t mind? It’s best to do things formally; and you can always have it later on when you want it.”
