A logline is a concise summary of the story in its entirety using (ideally) no more than 40 words phrased as a single sentence.

At 61 words and comprising of 3 sentences, I’d recommend checking out the Formula page (link in the top nav) or, better yet, try out the logline generator to help come up with a 1 sentence logline.

So she’s been given a job writing a book(?) about a wealthy philanthropist. I’m guessing she doesn’t have permission to do this? I feel like a book is a bit of a stretch and for a crime thriller (which I imagine this is) the shorter the time frame, the more potential you have for a thrill. Personally, I’d change her to be a journalist who uncovers a secret about the wealthy philanthropist she’s doing a positive story about. Have it so that she was commissioned by the philanthropist (or their agent) to write a nice piece about all the good work this guy does in the community. The paper she works for is being paid a substantial amount of money and given exclusive access for this piece. When she uncovers this secret, she’s caught between uncovering the truth – her natural instinct as a reporter – and the the knowledge that the paper will lose all that money and she may even lose her job. Dilemma. Then, as dpg said, MPR, she discovers she has a bounty on her head. So now she has to not only uncover the truth but also stay alive in order to do it.

As dpg also pointed out, the hook (the secret) is an important element and since it’s likely to happen as part of Act I, we do need a little more information to understand the story as a whole. This secret has to be big enough to warrant her risking her life.

Hope this helps.
