Step into the abyss

A woman fell to her death from the twenty-fifth floor terrace of a London bank. You are under arrest for her murder. You explain to the police that you met the victim the night before at a corporate party. She threatened to jump off the roof, but you talked her out of it. You have nothing to do with this tragedy. You are clearly being set up. So why do the police keep looking for weaknesses in your story? Even the lawyer doesn't seem to believe you. It is already clear to everyone that you are not telling something. But who are you trying to protect? Whose secrets are you keeping? And why? For the first time in Russian!
