Look inside the book:
To allow so young and delicate a girl to tramp England aimlessly in search of some vague and secret information which seemed to be her erratic father's object, was, we decided, an utter impossibility; therefore, following that night of our first meeting at Helpstone, Burton and his daughter remained our guests for a week, and, after many consultations and some little economies, we were at last successful in placing Mabel at school, a service for which we later received her heartfelt thanks. ...That the precious document, or whatever it was, sewn up in the wash-leather which the dead man had so carefully guarded through all those years was now missing was, in itself, a very suspicious circumstance, while Mabel's vague but distinct apprehensions, which she either would not or could not define, now aroused my suspicions that Burton Blair had been the victim of foul play.
