Why did the kings advisor wait until the last minute to stop the gunpowder plot?

The king's advisor likely waited until the last minute to stop the Gunpowder Plot to prevent any potential backlash against the crown and to maintain the element of surprise. By acting at the last moment, he could ensure that the conspirators were caught off guard, minimizing the risk of them escaping or executing their plan. Additionally, revealing the plot earlier might have compromised the investigation or allowed the conspirators to adapt their strategy. Ultimately, this approach served to protect the king and reinforce the stability of the monarchy.
