“Ah, I thought she wouldn’t register as Miss Mayhew,” was the detective’s comment. “I suppose a different name for each job. Well, gentlemen, we’ve got as much here as we can for the present. I don’t think we’ll stay any longer. I propose we adjourn to a café, have a drink and discuss our future plan of action.” They agreed with his suggestion. In their walk to a café close at hand, Grewgus did not speak much. His mind was no doubt busily working on the situation, and the best way of tackling it. When they were half-way through their drinks, he spoke. “We can’t hope to do very much this evening. Now what I propose is this, Mr. Lydon. I know Paris rather thoroughly, although I daresay my friend Simmons knows it better. This isn’t exactly a pleasure trip you’ve come on, and you won’t want to spend more money than is absolutely necessary. We must have something to eat, for that light meal at Boulogne wasn’t very satisfactory.” Lydon laughed. “I am in hearty agreement with you. The long journey has made me feel frightfully hungry.” “Well, if we go to one of the swagger places, you’ll be charged through the nose. This is the city _par excellence_ of good cooking, and I can take you to a capital little restaurant close by where everything is excellent, and you’ll pay about a third of the price. Their wines are good and reasonable too.” “I’m in your hands,” said the young man. “I should like you to take me along as soon as possible.” He noticed that Simmons did not appear to be included in the suggestion. The reason was explained when Grewgus turned to his colleague. “It’s not likely we shall be fortunate enough to do much to-night, as I said just now. We have had one big bit of luck to start with which has saved us a lot of time and trouble. All the same we won’t let our vigilance sleep. I want you to start on the watch at once, Simmons, if this woman and her mother come back. We shall be at the _Restaurant Grice_ for at least a couple of hours. If in the meantime there is anything to report, come to us there. If we have gone, come to the hotel.” The obedient Simmons finished his drink, rose up and went forth at once to obey his leader’s commands. After a final _apéritif_, Grewgus led his companion to the _Restaurant Grice_. Here they had a most excellent meal, consisting of a good soup, a sole worthy of the _Café Royal_, followed by some tender veal. They drank with it a white wine recommended by Grewgus. While they were eating, the detective dwelt regretfully on the vast difference between now and before the war. “If you knew the ropes, it was one of the cheapest places in the world to live in, and whatever you paid, you got splendid value for your money. Of course, very few of the English who came here _did_ know the ropes. I shouldn’t have known them but for a young fellow I met, a student in the Latin Quarter. Gad! What he didn’t know about Paris wasn’t worth knowing.”
