"Why, Juliet has gone to the dress rehearsal of the roof-garden show," he remembered. That was the word she had left with Togo to give him and Sanders on opening the door for them. But--Lyda was at the rehearsal! And she hadn't seen Juliet. Before sending such a message to him she would have made certain that the Duchess hadn't arrived! He would have Simone down at once! But Simone--the report came--was not in the house. She had gone out with Admiral Beatty, the Duchess's bull-dog. Neither Togo nor Huji could say when she was likely to return. But Togo made a suggestion. Nickson, the Duke's English valet, might know something of her movements. "Nickson!" echoed Jack, surprised. "This is a new development, isn't it, Nick knowing anything about Simone? I had an idea there was no love lost there." Togo ventured, on this encouragement, to smile dryly. At heart he had as little affection for Mademoiselle as Old Nick had. He would have liked to do her an ill turn in payment of many snubs, if it could be managed safely. "There is not much love, Captain," he said. "Perhaps that is why Mr. Nickson watches Mademoiselle when she takes the dog for a walk." "Is he afraid she'll do Beatty harm?" asked Jack. "I do not know, Captain. Mr. Nickson has not much talk. But perhaps he would answer some questions." "Is he in the house?" "Yes, Captain. I noticed he left soon after Mademoiselle, soon enough to see where she went--as he often does these days now His Grace is gone, and Mr. Nickson has not so much to keep him busy. But he is back." "Ask him to come here," said Manners. He spoke gravely, and as the respectful Togo retired, threw Sanders a puzzled look. "Is there anything in this?" he asked. "That's what I've been wondering myself," vouchsafed the detective. "You knew Old Nick was dogging Simone's footsteps?" "Yes, but I didn't know why. I've been trying to find out." "How?" "By having the said footsteps dogged on my own account." "You've had Simone shadowed?" "Certainly. But that doesn't necessarily imply suspicion. I'd be a poor sort of chap at my job if I didn't have every servant in the house shadowed." "Great Scott! And without a word to me or my cousin!" "I can't bother you two with every detail. Besides, she or you might have objected, and that would have made things awkward all around." "H'm! I see. Well, where does Simone go?" "She goes, quite naturally, to a French café where she can drink her native coffee and chat with compatriots in her native tongue." "Nothing much in that, then, it would seem." "No. Nothing much. Or--so it 'would seem', as you say." "All the same you're putting two and two together?" "That would be a mistake, from my point of view. The great thing is, to see whether two and two put themselves together." "Shall I come in, sir?" asked the man known to the household as "Old Nick," when his tap on the door left ajar for him had not been answered. "Yes, come in," said Jack.
