The tourist season has arrived in Portwenn. Disgruntled by the invasion of holidaymakers, Martin grimaces as he makes his way through the crowds. Then he notices an attractive woman, and stops to stare ... at her chest! She can't believe it when he says he'd like to examine her chest. Martin was actually trying to warn the woman about the dangers of sunbathing for fear of skin cancer, but his usual abrupt and quirky manner has caused offense. Gossip about the blood phobia which forced Martin to terminate his brilliant career as a surgeon seems to have spread round the village like wild fire. Two patients in the surgery can't resist mentioning the 'b' word to Martin. Then he gets an urgent call from the pub. Bert has had a terrible accident while working there, and he's bleeding profusely. The sight of blood pouring from Bert's wound begins to trigger the all too familiar panic attacks for Martin. But on closer examination he realizes the blood is actually tomato ketchup!
