Catcher belonged to a merchant family resident in the London area by the late fifteenth century.
How this restoration of his family’s financial fortunes was achieved is not known, but by 1621 Catcher headed a consortium, largely of London merchants, which bid for a lease to administer the duchy of Cornwall’s rights over the tin industry in Devon and Cornwall. Negotiations with the Duchy must have reached an advanced stage early that year, since the basic terms were agreed on 9 April. It was almost certainly to safeguard the deal against parliamentary criticism that Catcher entered the Commons that year, his election success at Truro on 26 Feb. doubtless assisted by his brother William, now an alderman of the borough.
The precise terms of the new tin monopoly have been lost, but the consortium offered an annual rent of £16,000, a full £7,000 per year more than the previous farmers, in return for a seven-year contract. Catcher had eight partners, but was liable for one sixth of any losses, presumably reflecting his overall share in the enterprise. However, notwithstanding his presumed inside knowledge of the industry, he was overreaching himself financially. In early December 1621, shortly before the contract took effect, he attempted to extricate himself from the deal, but failed to recruit a replacement. A month later Catcher raised £3,000 by selling property in London and Kent, and subsequently borrowed at least £4,000 more, but by mid-1622 he was in King’s Bench prison for debt.
Catcher was still in prison in July 1624, and it is unclear when he secured his release. He thought his brother Edward’s will worth challenging in 1627, even though the final settlement brought him only £200. He allegedly disposed of his Binfield lands while battling his creditors, but if so, he was back in possession by 1634, though conceivably as a lessee only.
