Then I told of my well-deserved ducking in the lake, admitting frankly that I had lied when I had said I could not swim, but pleading my cause and the excuses to be urged in my favour with all the eloquence at my command, and, judging by her increasing friendliness, not altogether without success.

"And now," I said, when I had made an end of it, "now about your brother and the kidnapping?"

"Yes," she replied, "we have to think of that. I expect you think that both Kate and I have taken it coolly, considering. But, you see, you don't know my brother. If you did, you'd have very little fear about his being able to take care of himself, wherever he is. What do you propose?"

"First of all," I said, "I'll ask you to ascertain whether the house is still being watched. You are taking me very much on trust, and if it should turn out that the shadower has returned to his post, or another shadower has been put on duty, it will go a little way to confirm my story, and to prove that I'm not altogether an impostor."

"I either trust people altogether, or don't trust them at all," she answered. "But you've been frank with me, so I'll tell you now that I haven't taken you so entirely upon trust as you imagine. There's an evening paper on that table which has an account of the finding of the bodies, just as you mentioned; and when I went upstairs to speak to my niece, I took the opportunity to peep up and down the road from behind the blinds. There is a man watching this house, and also a house somewhere in Taunton Square, just as you said. It certainly is very curious. Come in!"

The last two words were spoken in response to a knock. The door, when opened, revealed Metcalfe with a telegram on a salver. She read the slip of orange paper quite coolly, and then passed it to me, saying, "From my brother."

It was as follows:—

Hope Kate and you not anxious last night. Letter I wrote early yesterday morning explaining was called to Glasgow on business not posted by oversight. Only just discovered it in my pocket. So sorry. May be away some days.—John.

"So, you see, he's safe enough," Miss Clara said, smiling. "Do you really think you're right in thinking he is one of the millionaires they want to kidnap? I admit it is a curious coincidence that someone should be watching the house."

"Perhaps I have jumped to conclusions somewhat," I said. "But if someone is really watching the house again, I ought to be at work, not wasting any more of your time and my time by gossiping here—especially as it turns out after all that Mr. Carleton is safe. If there is any back door I could slip out by, I think I'll either follow the shadower myself, and see if I can't find out where he comes from, or perhaps even try to get New Scotland Yard to arrest him on suspicion. He's the only clue I've got to the whereabouts of the Dumpling, and it won't do for me to lose sight of him. What's that noise, I wonder, in the street? There's something amiss, clearly. It won't do for me to be seen leaving the house. Would you mind letting your servant inquire?"
