Take the following as truth: I presume Mrs. Inglethorp took the coffee after dinner about eight o'clock, whereas the symptoms did not manifest themselves until the early hours of the morning, which, on the face of it, points to the drug having been taken much later in the evening."
Then the following statement: "I assume Mrs. Inglethorp drank the coffee at night time so the symptoms didn't appear until five in the morning." is true, false, or inconclusive?
Answer: Inconclusive
