Lucia’s luncheon party next day was to be of the nature of a banquet to celebrate the double event of her recovery and of the fact that Tilling, instead of mourning her approaching departure, was privileged to retain her, as Elizabeth had said, for ever and ever. The whole circle of her joyful friends would be there, and she meant to give them to eat of the famous dish of lobster à la Riseholme, which she had provided for Georgie, a few weeks ago, to act as a buffer to break the shock of Foljambe’s engagement. It had already produced a great deal of wild surmise in the minds of the housewives at Tilling for no one could conjecture how it was made, and Lucia had been deaf to all requests for the recipe: Elizabeth had asked her twice to give it her, but Lucia had merely changed the subject without attempt at transition: she had merely talked about something quite different. This secretiveness was considered unamiable, for the use of Tilling was to impart its culinary mysteries to friends, so that they might enjoy their favourite dishes at each other’s houses, and lobster à la Riseholme had long been an agonising problem to Elizabeth. She had made an attempt at it herself, but the result was not encouraging. She had told Diva and the Padre that she felt sure she had ‘guessed it’, and, when bidden to come to lunch and partake of it, they had both anticipated a great treat. But Elizabeth had clearly guessed wrong, for lobster à la Riseholme à la Mapp had been found to consist of something resembling lumps of india-rubber (so tough that the teeth positively bounced away from them on contact) swimming in a dubious pink gruel, and both of them left a great deal on their plates, concealed as far as possible under their knives and forks, though their hostess continued manfully to chew, till her jaw-muscles gave out. Then Elizabeth had had recourse to underhand methods. Lucia had observed her more than once in the High Street, making herself suspiciously pleasant to her cook, and from the window of the garden-room just before her influenza, she had seen her at the back door of Mallards again in conversation with the lady of the kitchen. On this occasion, with an unerring conviction in her mind, she had sent for her cook and asked her what Miss Mapp wanted. It was even so: Elizabeth’s ostensible enquiry was for an egg-whisk, which she had left by mistake at Mallards three months ago, but then she had unmasked her batteries, and, actually fingering a bright half-crown, had asked point-blank for the recipe of this lobster à la Riseholme. The cook had given her a polite but firm refusal, and Lucia was now more determined than ever that Elizabeth should never know the exquisite secret. She naturally felt that it was beneath her to take the slightest notice of this low and paltry attempt to obtain by naked bribery a piece of private knowledge, and she never let Elizabeth know that she was cognisant of it.
