Take the following as truth: It told me that Mrs. Inglethorp had been writing the word 'possessed' that afternoon, and, having the fragment of paper found in the grate fresh in my mind, the possibility of a will, (a document almost certain to contain that word), occurred to me at once. 
Then the following statement: "I was worried that Mrs. Inglethorp had changed her will." is true, false, or inconclusive?
Answer: Inconclusive
