A law degree, three years in the CIA, and a black belt in Judo probably come in handy for author Barry Eisler. His John Rain series of novels are noted for their realistic depiction of compelling characters and edge-of-your-seat action. But Eislers left Rain at home this time for his latest title. A stand-alone story, Fault Line features a Silicon Valley lawyer, his black ops brother and a string of murders that leads right to them. 6 p.m. Murder by the Book, 2342 Bissonnet.
