"Damme!" cried Dunbar, "can your man be relied upon to watch them? They
mustn't slip away! Shall I instruct Perth to arrest the couple?"

Inspector Dunbar tapped his small, widely-separated teeth with the end
of his fountain-pen.

"I'll hand in my resignation if the Frys go!"

the biggest case of my professional career, or my name is not Robert
Dunbar!"
