Plot summary
An elderly woman who works at a rehabilitation center, Louise Politano ( Phyllis Somerville ), is killed by a booby trapped gift containing lye. Goren and Eames investigate her background and find that she may have faked a miraculous cure from polio in her childhood through faith in Brother Jerome, a 19th century healer who is currently being proposed for sainthood by the Brother Jerome Foundation. Investigation of supporting documents indicate that the authenticator engaged by the Foundation, James Bennett ( Stephen Colbert ), has been making money by forging and selling documents to the Foundation to support its case. He was motivated by revenge for the fact that over 20 years, his mother had given almost everything they owned to the Foundation. He killed Politano because she may have exposed his activities.
