Castle testifies as sole eyewitness in the murder case against the caterer at Roger and Joanna Masters' society party, where he was doing a book reading for charity. When the incompetent public defender who was on the case gets ill, Caleb Brown, who is suspected of working for LokSat, takes over and makes Castle admit he could be wrong. To cover for this and to shore up the case, Castle and the 12th precinct urgently re-check the evidence looking for alternative motives. What they find leaves Castle in doubt about what really happened.
