Overview: Tom is perplexed by carpenter Bert Cartwright's hostility to doctors until he learns that Bert blames Arthur for the death of his little boy years earlier. When Annie,Bert's wife, falls ill, Bert resists her hospitalisation but ,in her delirium, she mistakes Michael for her son who 'watches over her' and agrees to go, saving her life. Michael finds ancient coins in the woods but when the Reverend Brewer and station master Wilf start digging for treasure they unearth an unexploded bomb. Fortunately ex-munitions worker Phyllis knows how to defuse it - or thinks she does,but at least the remainder of the coins are unearthed.
