Answer:
When Henry was handed the envelope and he saw a bank note inside,he went into spending it.
Step-by-step explanation:
At initial Henry did not realize the power in his hands. His first attempt at spending the note in a local dining opened his eyes to the possibility of what has come to him. When he pulled out the note and Harris asked him not pay for the food, little did he know that he was a subject of bet. The note from the brothers A and B which details the terms of the bet to him, made matters worse. Every thinking to convert the note to money was defeated by fear of arrest and persecution. His second attempt to spend the note at suit shop made it clear to him that the note could take him far. He was offered a full wardrobe of suits, he changed his rags and his popularity grew exponentially. He became the popular vest-pocket monster.
His sudden rise to celebrity opened another vista fro him, where Harris had to lend him money. However, that did not make him to loose focus to avoid over borrowing.
His fame started earning him big invitations to important events, which introduced him to important personalities. It was in one of the meeting that he met the British woman, Portia Langham and the mining deal that came with it.
The situation changed Henry's life when Portia reveled to him that Brother B is her step father, despite turning down the situation initially, he humbled himself to request for the situation as his step son.
He used the opportunity that came with the million pounds bnak to note to lift himself from penniless and rags to fame and rich man.
