Take the following as truth: When I went up to Styles with you that first day, I had no idea as to how the crime had been committed, but from what I knew of Mr. Inglethorp I fancied that it would be very hard to find anything to connect him with it. 
Then the following statement: "I knew it was Mr. Inglethopr who had committed the crime." is true, false, or inconclusive?
Answer: False
