“If you had been here, two nights ago, you would have seen your humble servant at the top of a ladder, about to enter the château by that window.”
As I expressed some surprise at this piece of nocturnal gymnastics, he begged me to notice carefully the exterior disposition of the château. We then went back into the building.
“I must now show you the first floor of the château, where I am living,” said my friend.
To enable the reader the better to understand the disposition of these parts of the dwelling, I annex a plan of the first floor of the right wing, drawn by Rouletabille the day after the extraordinary phenomenon occurred, the details of which I am about to relate.
1. Position where Rouletabille placed Frédéric Larsan.
2. Position where Rouletabille placed Daddy Jacques.
3. Position where Rouletabille placed Monsieur Stangerson.
4. Window by which Rouletabille entered.
5. Window found open by Rouletabille when he left the room. He re-closed it. All the other doors and windows were shut.
