Food in A Question of Death - Beouf en Daube

In Putin on the Ritz Mrs Veale ordered boeuf en daube. Phryne convinces her she dropped her pearls in the dish causing them to dissolve. I tried cooking my own here is the recipe:

Ingredients:
1 kg lean beef
1 tbs flour
2 onions, sliced
1 clove garlic, crushed
2 slices bacon, diced
1 bouquet garni or a small bunch containing one sprig each of thyme, chervil and parsley
2 zucchini, sliced
1 green pepper, sliced and deseeded
1 tbspn of olive oil
1 finger sized bit of orange peel
250 g stoned black Kalamata olives
500 ml red wine
A pinch of salt
Freshly ground black pepper

Method:
Dice the meat and coat it with flour. Fry the onions and garlic. Throw in the meat and cook gently
until it is browned. Pour the wine and all the other ingredients into the pan, and stir gently over low
heat until it has all combined and begins to look silky. If it looks a bit dry, pour in another 500 ml of
water, and if it still absorbs liquid add some more wine.

Put this in a very slow oven for about three hours, or longer if your guests are always late. This
peasant dish is from the south of France
