“As you like.” May drew out his watch. “It’s after nine,” he added, “if we are going to the Casino we had better be t-toddling.”

On the way there May entered a tobacconist’s, and Lenox waited for him without. As he loitered on the curb, Blydenburg rounded an adjacent corner.

“Well,” exclaimed the latter, “you didn’t see our friends off.”
