“On this side of the house from front to back, we have the reception-room where Mr. Harrison was killed, then this library, then the hall beyond the armor there and then the billiard-room. Beyond that lies the sunken garden.

“The plan of the wing is the same on all three floors; a suite of two bedrooms and a bath facing the front of the house and a similar suite facing the rear. The suites are separated by a long hall. At the end of the wing toward the rear, a servants’ staircase and fire escape runs from the ground floor to the third floor. On the second and third floors there is a window at the end of the hall. On this floor there is a door leading out to the garage.”

“Are any of the wing bedrooms occupied on this floor?” inquired Landis.

“Mr. Allen occupies the rear bedroom toward the end of the hall on the ground floor and has the use of the adjoining bath this side of it. Mr. Russell occupies the far front bedroom and uses the adjoining bath. The front and rear bedrooms next the main building are unoccupied.”

Bernard got to his feet and glanced at Landis.

“Believe I’ll have a look at the wing again and get that clear,” he said. “Like to come?”

The others, including Miss Mount, rose to their feet. Landis and Graham prepared to follow Bernard and Miss Mount. Brent glanced at the big desk and moved toward it.

“I’ll stay here,” he said, “and look over Mr. Harrison’s papers. That is my duty as executor—”

“That’s perfectly all right, Mr. Brent,” Landis cut in courteously. “Only please don’t change the position of anything or remove anything until we have examined the desk. There may be something there that will help us.”
