When a highly respectable real estate attorney stumbles on the bullet-ridden body of a client, he must investigate his own firm to uncover their involvement in the murder.

Thanks for your feedback. Here's a revised logline.

When a highly respectable real estate attorney stumbles on the bullet-ridden body of a client, he must investigate his own firm to save his reputation.

Do you think this better explains why he does not call the police?

Thanks again.

"...he must investigate his own firm to uncover their involvement in the murder."

Needs an 'and/or' - otherwise, there's no "push" for the main character, he might as well just call the police.

Thank you for your positive feedback.

This is a really good logline. The complexity of the protagonist's situation is immediately present. Good job!
