On the other hand, like all these stout, little men who do themselves well, he is a plethoric sleeper. Agatha⁠—that’s my fiancée⁠—says it is a joke in the servants’ hall that it’s impossible to wake the master. He has a secretary who is devoted to his interests, and never budges from the study all day. That’s why we are going at night. Then he has a beast of a dog which roams the garden. I met Agatha late the last two evenings, and she locks the brute up so as to give me a clear run. This is the house, this big one in its own grounds. Through the gate⁠—now to the right among the laurels. We might put on our masks here, I think. You see, there is not a glimmer of light in any of the windows, and everything is working splendidly.”
