Strangers on a Train

After David witnesses a man getting thrown off a moving train, it leads to Steve foiling an armed robbery at Ashfordly Hall, but also leaves an escaped convict loose in Aidensfield. As the team pursue him, Ventress feels lost without the police force and is delighted when Merton comes up with a solution. Meanwhile, Vernon is stalked by a donkey, but later turns it to his advantage by opening up a donkey sanctuary, only to have his plans opposed when he discovers a sanctuary already exists in the village.
