Friends of missing Hertfordshire author Helen Bailey have spent the day taking part in an organised dog walk - in the hope that it will keep the search for her fresh in people's minds.
The 51-year-old was last seen walking her Miniature Dachshund Boris in Royston six weeks ago.
Neither she or the dog have been seen since.
Today's event in Royston was organised by local dog owners - including the breeder Helen got Boris from.
Helen, who has had seven-year-old Boris since he was a puppy, is a member of the Royston Dog Walkers group on Facebook.
