If they knew anything, they would not question people in this manner , said d’Artagnan to himself. Now, what is it they want to know? Why, they want to know if the Duke of Buckingham is in Paris, and if he has had, or is likely to have, an interview with the queen.

D’Artagnan held onto this idea, which, from what he had heard, was not wanting in probability.

In the meantime, the mousetrap continued in operation, and likewise d’Artagnan’s vigilance.

On the evening of the day after the arrest of poor Bonacieux, as Athos had just left d’Artagnan to report at M. de Tréville’s, as nine o’clock had just struck, and as Planchet, who had not yet made the bed, was beginning his task, a knocking was heard at the street door. The door was instantly opened and shut; someone was taken in the mousetrap.
