Naturally, Dr. Henry is something of a cheapskate.  A dangerous cheapskate.<br/><br/>The main reason why he's an easy mark isn't that he's gullible.  It's that he's dangerously overconfident, from being too keenly aware of his surroundings.<br/><br/>Naturally, the main things that keep him in command are his complete lack of ethics and willingness to take any unreasonable compromise.   ;)
