4th entry - Dr Armstrong

At this point, i have to question the sanity of many of the guests on this island, although i know not of mental illnesses, i have a strong gut feeling that general McArthur has something wrong.  I think i may be losing it myself, i mean just after pondering whether or not this McArthur man is alright and now he is dead, and this one no accident indeed.  I am greatly concerned for my safety and sanity and must get off this crazy, homicidal island before i lose it.  I also find it greatly disturbing that a killer is amoungst us and the possibilities of who the killer could be are greatly wearing down, i am fearing that the killer is much closer then i could ever imagine.
