I understand your desire to keep this investigation within your own bureau, but there is no way we can train one of your agents in time. As you told me initially, Gulf Stream's CEO is agreeing to put a man in place =only= if he's qualified for the cover.
However, let me reassure you about Keith Hellman. As my unit's best investigator, he is a Federal Marshal with five years' experience. We've sent him undercover before. Also, he's been a diver for over twenty years, an important skill for anyone working out at Gulf Stream.
You really aren't going to find anyone better.
