I have finished my first novel, A Murder in Our Midst (William Turner), which is available on Amazon.com and at Barnes and Noble. I am starting my second, which I've outlined. I am stuck, however, because I can't find the poison I want to use in my book. I am looking specifically for a poison that would take 3-4 days to take full effect. The poison I'm looking for would have to be easily administered--by a novice--and the poison would take effect gradually; for example, with flu-like symptons--symptons that would not cause alarm.
