The chief motioned to Chettle, who went off with the hall-porter; he himself followed the manageress into her office. She unlocked a safe, rummaged amongst its contents, and handed him a small square parcel, done up in brown paper and sealed with black wax. Before he could open it, Chettle returned, serious and puzzled, and whispered to him. Then, with the shortest of leave-takings, the two officers hurried away from the Pompadour, the chief carrying the little parcel tightly grasped in his right hand.

CHAPTER XXXI

THE HYDE PARK TEA-HOUSE

Once outside the Pompadour Hotel the chief and his subordinate hurried at a great pace towards the Lancaster Gate entrance to Kensington Gardens. And when they had crossed Bayswater Road the superior pulled himself up, took a breath, and looked around him.

"No sign of them yet, Chettle," he observed. "Did he say at once?"

"Said they'd be on their way in two minutes, sir," answered Chettle. "And it wouldn't take them many minutes to run up here."

"I wonder what it's all about?" mused the chief. "Some new development since we left the Yard, of course. Well—I think we may probably find something in this parcel, Chettle, that will surprise us as much as any new development can possibly do. It strikes me—"

"Here they are, sir!" interrupted Chettle. He had lingered on the kerb, looking towards the rise of the road going towards the Marble Arch, and his quick eyes had spotted a closed taxi-cab which came out of the Marlborough Gate at full speed and turned down in their direction. "Blindway and two others," he announced. "Seems to be in force, sir, anyhow!"

The taxi-cab pulled up at the little gate leading into Kensington Gardens by the pumping-station, and Blindway, followed by two other men, hurriedly descended and joined his superior.

"Well, what is it?" demanded the chief. "Something new? And about this affair?"
