Dirty Len - S12.E7

Mike searches for a link between a dead farm worker and a spate of animal deaths. Alfred leaves David high and dry in Whitby.

Meanwhile Tricia is upset, because of her patient dieing. She soon starts to feel guilty over the death of Len. She thought that it was tetanus but lad results come back with poison and she blames herself for not picking up on it. Even though there was nothing she could have done she still blames herself and feels that she was bad doctor.
