In 1595 Horsey was accused of high treason by Finch, whom he had caused to be sent home from Moscow. It is thought that Finch was put up to this by Sir Jeremy Bowes, the ex-ambassador to Moscow, who thought that Horsey had caused him to be sent home by the Russians. Among other things, Horsey was stated to have said "Our Virgin Quene is no more a virgin than I am". The queen had no choice but to sign a warrant for his arrest, but she said "I still believe Jerome Horsey will prove himself honest". The case came before the Privy Council in April 1597 but was dismissed, and Finch was proved to be a liar by witnesses.
