Murder Beyond Recall

Investigating a violent death, which happened a long time ago, and which everyone has forgotten about, may not be the best thing for a newly employed young gardener with too much time on his hands to become involved in to pass some of that time. Especially when his investigations bring to light evidence of a miscarriage of justice which happened at the time, and which resulted in someone being executed for a crime they didn't commit. And even more especially when it turns out that the true perpetrator of the crime is still around to ensure that nobody else gets to see the new evidence the young man has uncovered.
