 James and Tristan drive back from a conference in London and Tristan promptly drives the car through the garage wall. Tristan gets a visit from a Edinburgh friend, Alice McTavish, who has  wee Tristan  in tow. There s a simple explanation but Sigfried jumps to conclusions. Tristan is obviously very keen on Alice and starts thinking about more permanent arrangements. James treats the Barratts  dog; they are clearly an unhappy couple on the verge of a separation.
