“Most of the Germans,” he said to her, “you will find are very methodical. They like to do things according to schedule. For instance, I learned yesterday that old Hoff and his nephew frequently go off on all-day automobile trips. They always go on Wednesday.”
“Are they going to-morrow?”
“The presumption is that they will. They have done so every Wednesday for six weeks.”
“Can’t we follow them in our car?” cried the girl, “and see what they are up to?”
Dean shook his head.
“The Chief is looking out for that. There is more important work for us to do right here. I want to try to install a dictograph in their apartment.”
“How exciting.”
“You must find some excuse for me to come up into your apartment and see to it that none of your people are about.”
“That will be easy. Mother and Aunt will be out all day, and it is cook’s afternoon off. I can easily send the maids out.”
“But that’s not all. There is the Hoffs’ servant to be disposed of.”
