Pharmakon

I just finished PHARMAKON BY DICK WITTENBORN and this book was a total waste of time. The story could have been great but ended up completely pointless. I don't think Dick knew which book he wanted to write. This story started out like three different books. A psychologist does research for a drug and one of his patients goes crazy and tries to murder him. Then he escapes and meets his son. Then he goes away and completely disappears from the story except as some inescapable fear. I don't know where this story was going but it just ends with the psychologist in his mid seventies, his wife in the hospital and his children unresolved. What a waste of hours of my time. Please don't waste yours.
