In the trial that followed, it was revealed that the nurse, Ted Maher, had set the blaze hoping to carry out a rescue mission from which he would emerge a hero, but lost control of the fire. A group of firefighters arrived and attempted to save Safra, but they were unable to find him. He had barricaded himself, along with an employee, inside a bathroom, the door of which the firefighters were unable to locate because it was camouflaged to match the rest of the elaborately decorated bedroom.

Even if you’re not a billionaire, it’s useful to remember two rules:

1. Don’t hire assistants who have hero complexes.
2. Your doors should look like doors.
