I do not see any colorful setup. There is no crowd seen either. It is not dark also. As the fire breathers like to perform when it is dark and when there is remarkable crowd.

Lucas putting down the phone went to the shower to take a special bath. Finishing the bath he went to the roof fully wet. His house is far from the meddling crowd. He took the pills which he made with all his expertise of Chemistry. 'It is time,' he thought.
He ignited the fire torches he bought from a fire breather at the street several night earlier. With extra caution he juggled them then all of a sudden he put the fire on him and in him. Within a moment fire spread all over his body not only outside was burning but also his inside was burning too. If anyone had seen him then, would saw a fire dancing upon further close inspection, you can see him laughing maniacally!
Human body is so wonderfully crafted, due to the lack of Oxygen and huge water portion, it is hard for fire to burn inside. That is the reason Lucas invented the 'Blood of Unicorn' whic creates such an environment, it is not tough for fire to burn inside.
When his friend arrived, he only found a lump of burnt flesh and bones!
No one knew why a renowned scientist who everyone thoght of to be eligible to bag the noble prize in Chemistry died a horrible death!
