“Then you’re not satisfied about the circulation?” Blake inquired, and Kit thought his interest rather keen.

“We are nearly satisfied. Colvin’s hurrying me, and when Mabel has had enough I must go back to the office: the tube-shop foreman wants some particulars. Anyhow, we mustn’t bore Mabel. I like your window, madam. It commands a moving view.”
