Lady Fenwick, provoked at this cruel outrage, prevailed upon her nephew the earl of Carlisle to move the house that sir John might be examined touching any advices that had been sent to him with relation to his discoveries.

Fenwick being interrogated accordingly, gave an account of all the particulars of Monmouth's scheme, which was calculated to ruin the duke of Shrewsbury by bringing Smith's letters on the carpet.

The duchess of Norfolk and a confidant were examined and confirmed the detection.

The house called for Smith's letters, which were produced by sir William Trumball.

The earl of Monmouth was committed to the Tower and dismissed from all his employments.
