“The floor below?”

“It’s all occupied by a modiste, Renan.”

“The top floor?”

“Cubanis Cigarette Company, a servants’ and an electrician.”

“Nae more?”

“No more.”

“Where does yon back stair open on the topmaist floor?”

“In a corridor similar to that alongside Kazmah’s. It has two windows on the right overlooking a narrow roof and the top of the arcade, and on the left is the Cubanis Cigarette Company. The other offices are across the landing.”

Mary Kerry stared into space awhile.

“Kazmah and Mrs. Irvin could ha’ come down to the fairst floor, or gene up to the thaird floor unseen by the Spinker man,” she said dreamily.
