Take the following as truth: On that day, Mrs. Inglethorp's bell wire was neatly cut, and on Monday evening Mademoiselle Cynthia was spending the night with friends, so that Mrs. Inglethorp would have been quite alone in the right wing, completely shut off from help of any kind, and would have died, in all probability, before medical aid could have been summoned. 
Then the following statement: "Madamoiselle Cynthia was with Mrs. Inglethorp that night." is true, false, or inconclusive?
Answer: False
