Bell paused as the telephone bell rang out shrilly. The mere sound of it thrilled both of them with excitement. And what a useful thing the telephone had proved!

"Are you there?" came the quick, small whisper. "Is that you, Mr. Steel?
I am Enid Henson."

There was a long pause, during which David was listening intently. Bell could see him growing rigid with the prospect of something keen, alert, and vigorous.

"Bell is here with me at this moment," he said. "Just wait a minute whilst I tell him. Don't go away, please. Under the circumstances it might be dangerous for me to ring you … Just a moment. Here's a pretty mess."

"Well," Bell said, impatiently, "I'm only a mere man, after all."

"Henson is at Longdean; he turned up an hour ago, and at the present moment is having his supper in the library before going to bed. But that is not the worst part of it. Williams heard the dogs making a great noise by the gates, and went to see what was wrong. Some poor, demented fellow had climbed over the wall, and the dogs were holding him up. Fortunately, he did not seem to be conscious of his danger, and as he stood still the hounds did him no harm. Williams was going to put the intruder into the road again when Miss Henson came up. And whom do you suppose the poor, wandering tramp to be?"

Bell pitched his cigar into the grate full of flowers and jumped to his feet.

"Van Sneck, for a million," he cried. "My head to a cocoanut on it."

"The same. They managed to get the poor fellow into the house before Williams brought Henson from the lodge, and he's in the stables now in a rather excited condition. Now, I quite agree with Miss Henson that Henson must be kept in ignorance of the fact, also that Van Sneck must be got away without delay. To inform the hospital authorities would be to spoil everything and play into Henson's hands. But he must be got away to-night."

"Right you are. We'll go and fetch him. Et apres?"
