Justice Lawrence Wargrave - Interesting Conversation

I wonder who will be next. I strongly believe that the killer is among one of the guests in this house. There is just no way that Mr. Owens has evaded all of the guests’ sight for the past few days. There is so much evidence that he is not one of the guests, but I have a strong gut feeling that someone has been lying this whole time.
I have considered everybody for all of the murders but I could not single out any one individual, as it could be anybody. I am sure the other guests have all been suspicious about me, but it could be for good reason. I have taken charge of them right from the start. I am however, particularly suspicious about Dr. Armstrong. Two of the deaths were due to poisoning, and Dr. Armstrong is the most likely candidate to possess those types of drugs. For General MacArthur, Armstrong could just as easily say that MacArthur’s body was dead for an hour, while avoiding all suspicion. Lombard is the only guest that possesses a gun, but none of the accidents were related to any type of shooting. Plus, Indian Island is so small, it would be simple to hear a gunshot. Mrs. Brent has been quiet this whole time, but not to the point where she has been ruled out as the “Mr. Owen.” I am sticking to my word when I say anybody on the island could be the potential killer.
