At the murder scene the killer has left a written paper with the following words:"HE WAS MORE CLEVER THAN ME, RICHER THAN ME, MORE GENEROUS THAN ME, TALLER THAN ME, MORE HANDSOME, SMARTER, MORE SELF-CONFIDENT, HE DRESSED BETTER THAN ME, HE SPOKE BETTER THAN ME; IF YOU THINK THAT THESE ARE EXCUSES, YOU ARE SILLY. I HAVE ALWAYS THOUGHT ABOUT HOW TO GET RID OF HIM. I MADE A MISTAKE POISONING HIM: HE SUFFERED TOO MUCH. I AM SORRY ABOUT IT. I WOULD HAVE PREFERRED HE HAD DIED QUICKLY."
