Gently Sahib

If a tiger mauled a man to death, would he bother burying the corpse?An escaped tiger that terrorizes a little market town is shot dead by a police marksman, having caused nothing more than a minor panic. A year later, a man is found mauled to death and neatly buried in his own back garden. The only thing Gently can be sure of is that the tiger didn't bury the body, so who did?
