Mark A. Vieira writes that he will be signing advance copies of his book “Into the Dark” at the TCM Classic Film Festival. “Into the Dark,” published by Running Press and TCM, won’t be officially released until May 24, so this is an opportunity to be one of the first to get the book. Mark is scheduled to be signing “Into the Dark” on the lobby stage of the Roosevelt Hotel on April 29 from 1 p.m. to 2 p.m.
