Mrs.Rheinholdt was suddenly aware that she was becoming a little tactless.
"Of course," she sighed, "it is disappointing not to be able to lay your hands upon the thief.

That is where I suppose you must find the interference of an amateur like Mr.Quest a little troublesome sometimes.
He gets back the property, which is what the private individual wants, but he doesn't secure the thief, which is, of course, the real end of the case from your point of view." "It's a queer affair about these jewels," the Inspector remarked.

"Quest hasn't told me the whole story yet.

Here we are on the stroke of time!" The car drew up outside Quest's house.

The Inspector assisted his companion to alight and rang the bell at the front door.
