Midsomer-in-the-Marsh
A disputed sighting of an African bird leaves a village ornithology club divided before one of its members is killed.

Casebook interpretation
Welcome to Midsomer-in-the-Marsh
Midsomer-in-the-Marsh is principally known through one case, making this a compact story-location file rather than a claim to a complete village history. Its recorded case material places it in the Casebook's eccentric territory.
Editorial interpretation Where the programme has not established a resident, building or piece of geography, the Casebook leaves it unstated rather than turning inference into canon.
