For the detective had been provided with a means of entering that house at any hour of the day or night without calling upon the servants to admit him. When he entered it that night, he took himself straight to the room where the big teester bed was located, and where the ambassador slept.

“You had the forethought to escape,” said the ambassador, when he was able to speak after he had heard the story. “Heavens, Mr. Carter, think of the fix you would be in if you had been captured.”

“Eh? Why do you say that, prince?”
