Take the following as truth: I do not think, monsieur, said Poirot pointedly, "that you quite realize how terrible it may be ”for you." And as Inglethorp did not appear to understand, he added: "Mr. Inglethorp, you are standing in very grave danger." The two detectives fidgeted. 
Then the following statement: "Mr. Inglethorp ignored Poirot's warning and was murdered." is true, false, or inconclusive?
Answer: Inconclusive
