Monsieur Jacques bowed low and smiled.

"I have enjoyed the permission of visiting it, by the kindness of Sir Jekyl's man."

"He does not suppose any object?" inquired Monsieur Varbarriere.

"None in the world—nothing—merely the curiosity of seeing everything which is common in persons of my rank."

Monsieur Varbarriere smiled dimly.

"Well, there is a room opening at the back of Sir Jekyl's room—what is it?"

"His study."

Varbarriere nodded—"Go on."
