A very good episode where an investigation into a man who is hit over the head, then later dies from a heart attack. Morse and Lewis have plenty of suspects but vital evidence - a tape - is missing.
When they arrest a young man who refuses to tell them anything until after his mother dies, certain facts come to light.
It isn\'t until the rest of the pieces of the puzzle come together when Morse is looking at a holiday magazine that the tragic truth behind the first murder is revealed but not before another person is murdered.
A tragic tale of what can happen when people prey on children. Well written and sensitively portrayed.
