Thomas Claffin (played by Brian Gleeson) is the head of Claffin Insurance in the Apple TV series Bad Sister.  After Grace Williams' husband dies, Thomas recruits his brother Matthew to help him investigate the associated life insurance claim.  His goal is to find that the Garvey sisters Eva, Ursula, Bibi, and Becka have murdered their brother-in-law so they do not have to pay the claim out and bankrupt their company while his wife is heavily pregnant.  Thomas dresses much more professionally than his brother, typically wearing plain suits and coordinated ties while investigating the sisters.
