Miss Marple's final cases - Agatha Christie [13]
‘A damned cookery recipe. Baked ham!’
Charmian was untying a ribbon that held the letters together. She drew one out and glanced at it. ‘Love letters!’
Miss Marple reacted with Victorian gusto. ‘How interesting! Perhaps the reason your uncle never married.’
Charmian read aloud:
‘ “My ever dear Mathew, I must confess that the time seems long indeed since I received your last letter. I try to occupy myself with the various tasks allotted to me, and often say to myself that I am indeed fortunate to see so much of the globe, though little did I think when I went to America that I should voyage off to these far islands!” ’
Charmain broke off. ‘Where is it from? Oh! Hawaii!’ She went on:
‘ “Alas, these natives are still far from seeing the light. They are in an unclothed and savage state and spend most of their time swimming and dancing, adorning themselves with garlands of flowers. Mr Gray has made some converts but it is uphill work, and he and Mrs Gray get sadly discouraged. I try to do all I can to cheer and encourage him, but I, too, am often sad for a reason you can guess, dear Mathew. Alas, absence is a severe trial for a loving heart. Your renewed vows and protestations of affection cheered me greatly. Now and always you have my faithful and devoted heart, dear Mathew, and I remain—Your true love, Betty Martin.
‘ “PS—I address my letter under cover to our mutual friend, Matilda Graves, as usual. I hope heaven will pardon this little subterfuge.” ’
Edward whistled. ‘A female missionary! So that was Uncle Mathew’s romance. I wonder why they never married?’
‘She seems to have gone all over the world,’ said Charmian, looking through the letters. ‘Mauritius—all sorts of places. Probably died of yellow fever or something.’
A gentle chuckle made them start. Miss Marple was apparently much amused. ‘Well, well,’ she said. ‘Fancy that, now!’
She was reading the recipe for baked ham. Seeing their enquiring glances, she read out: ‘ “Baked ham with spinach. Take a nice piece of gammon, stuff with cloves, and cover with brown sugar. Bake in a slow oven. Serve with a border of pureed spinach.” What do you think of that, now?’
‘I think it sounds filthy,’ said Edward.
‘No, no, actually it would be very good—but what do you think of the whole thing?’
A sudden ray of light illuminated Edward’s face. ‘Do you think it’s a code—cryptogram of some kind?’ He seized it. ‘Look here, Charmian, it might be, you know! No reason to put a cooking-recipe in a secret drawer otherwise.’
‘Exactly,’ said Miss Marple. ‘Very, very significant.’
Charmian said, ‘I know what it might be—invisible ink! Let’s heat it. Turn on the electric fire.’
Edward did so, but no signs of writing appeared under the treatment.
Miss Marple coughed. ‘I really think, you know, that you’re making it rather too difficult. The recipe is only an indication, so to speak. It is, I think, the letters that are significant.’
‘The letters?’
‘Especially,’ said Miss Marple, ‘the signature.’
But Edward hardly heard her. He called excitedly, ‘Charmian! Come here! She’s right. See—the envelopes are old, right enough, but the letters themselves were written much later.’
‘Exactly,’ said Miss Marple.
‘They’re only fake old. I bet anything old Uncle Mat faked them himself—’
‘Precisely,’ said Miss Marple.
‘The whole thing’s a sell. There never was a female missionary. It must be a code.’
‘My dear, dear children—there’s really no need to make it all so difficult. Your uncle was really a very simple man. He had to have his little joke, that was all.’
For the first time they gave her their full attention.
‘Just exactly what do you mean, Miss Marple?’ asked Charmian.
‘I mean, dear, that you’re actually holding the money in your hand this minute.’
Charmian stared down.
‘The signature, dear. That gives the whole thing away. The recipe is just an indication. Shorn of all the cloves and brown sugar and the rest of it, what is it actually? Why, gammon and spinach to be sure! Gammon and spinach! Meaning—nonsense! So it’s clear that it’s the letters
