Der Blutdiamant [prev. Die Blutdiamanten Von Rabuun]

Valentin Smitt is a wealthy private banker. His business activities and unusual lifestyle regularly take him around the world. In recent years, however, Valentin has undergone a strange change from a serious, successful and popular businessman to a more withdrawn, selfish hermit existence. Since then, people have been saying behind his back that he made his fortune through dubious deals and at the expense of others, but there has been no evidence of this so far. Valentin is said to have earned a lot of money in particular from trading diamonds. One of these diamonds is said to be of inestimable value and is still in his possession, as you learned from an informant. You are a team of private investigators and you want to find exactly this diamond as evidence of Valentin's dubious machinations. You know that Valentin is at a business meeting today and won't be back for another hour. Can you find the diamond in this time?
