He wants to get his hands on Clarence and, most importantly, on the money she would inherit in the eventuality of her new husband's death. Diaz makes attempts on Hannibal's life.

The inspector tries to solve the countless mysteries. In this, he is joined by Allan, always ahead of the man of the law in his estimation and judgment of the situation.
