Heir to the one of the few conspirators engaged in the Bye Plot to be executed for treason, Brooke suffered the loss of his patrimony by attainder in 1606.
Brooke was heir to the 11th Lord Cobham, who died childless in 1619, but he was prevented from inheriting either the Cobham lands or title by the very Act that enabled him to recover Cooling in 1610. This condition of his restoration undoubtedly rankled, and may help explain his involvement in an attempt to unseat the royal favourite, the marquess of Buckingham, in January 1618. Along with Sir William Monson* and Sir Henry Mildmay*, he was brought to James’s attention in January 1618 by the Howards.
Returned to Parliament for Rochester in 1628, Brooke left no trace on its records. While serving in the Commons, he presented a fellow graduate of St. John’s College, Cambridge, Nathaniel Sparke, to the rectory at Cooling.
