Take the following as truth: Poirot seized his hat, gave a ferocious twist to his moustache, and, carefully brushing an imaginary speck of dust from his sleeve, motioned me to precede him down the stairs; there we joined the detectives and set out for Styles. 
Then the following statement: "I was not sure if Poirot and I would be useful or in the way of the detectives." is true, false, or inconclusive?
Answer: Inconclusive
