Take the following as truth: I was now sure that one, or possibly both of the gardeners, for there were two sets of footprints in the bed, had entered the boudoir, for if Mrs. Inglethorp had merely wished to speak to them she would in all probability have stood at the window, and they would not have come into the room at all. 
Then the following statement: "There were no footprints outside the bedroom." is true, false, or inconclusive?
Answer: False
