Miss Mapp had a mind that was incapable of believing the improbable, and the current explanation of these late hours was very improbable, indeed. Major Flint often told the world in general that he was revising his diaries, and that the only uninterrupted time which he could find in this pleasant whirl of life at Tilling was when he was alone in the evening. Captain Puffin, on his part, confessed to a student's curiosity about the ancient history of Tilling, with regard to which he was preparing a monograph. He could talk, when permitted, by the hour about the reclamation from the sea of the marsh land south of the town, and about the old Roman road which was built on a raised causeway, of which traces remained; but it argued, so thought Miss Mapp, an unprecedented egoism on the part of Major Flint, and an equally unprecedented love of antiquities on the part of Captain Puffin, that they should prosecute their studies (with gas at the present price) till such hours. No; Miss Mapp knew better than that, but she had not made up her mind exactly what it was that she knew. She mentally rejected the idea that egoism (even in these days of diaries and autobiographies) and antiquities accounted for so much study, with the same healthy intolerance with which a vigorous stomach rejects unwholesome food, and did not allow herself to be insidiously poisoned by its retention. But as she took up her light aluminium opera-glasses to make sure whether it was Isabel Poppit or not who was now stepping with that high, prancing tread into the stationer's in the High Street, she exclaimed to herself, for the three hundred and sixty-fifth time after breakfast: "It's very baffling"; for it was precisely a year today since she had first seen those mysterious midnight squares of illuminated blind. "Baffling," in fact, was a word that constantly made short appearances in Miss Mapp's vocabulary, though its retention for a whole year over one subject was unprecedented. But never yet had "baffled" sullied her wells of pure undefiled English.
Movement had begun; Mrs Plaistow, carrying her wicker basket, came round the corner by the church, in the direction of Miss Mapp's window, and as there was a temporary coolness between them (following violent heat) with regard to some worsted of brilliant rose-madder hue, which a forgetful draper had sold to Mrs Plaistow, having definitely promised it to Miss Mapp . . . but Miss Mapp's large-mindedness scorned to recall the sordid details of this paltry appropriation. The heat had quite subsided, and Miss Mapp was, for her part, quite prepared to let the coolness regain the normal temperature of cordiality the moment that Mrs Plaistow returned that worsted. Outwardly and publicly friendly relationships had been resumed, and as the coolness had lasted six weeks or so, it was probable that the worsted had already been incorporated into the ornamental border of Mrs Plaistow's jumper or winter scarf, and a proper expression of regret would have to do instead. So the nearer Mrs Plaistow approached, the more invisible she became to Miss Mapp's eye, and when she was within saluting distance had vanished altogether. Simultaneously Miss Poppit came out of the stationer's in the High Street.
Mrs Plaistow turned the corner below Miss Mapp's window, and went bobbing along down the steep hill. She walked with the motion of those mechanical dolls sold in the street, which have three legs set as spokes to a circle, so that their feet emerge from their dress with Dutch and rigid regularity, and her figure had a certain squat rotundity that suited her gait. She distinctly looked into Captain Puffin's dining-room window as she passed, and with the misplaced juvenility so characteristic of her, waggled her plump little hand at it. At the corner beyond Major Flint's house she hesitated a moment, and turned off down the entry into the side street where Mr Wyse lived. The dentist lived there, too, and as Mr Wyse was away on the continent of Europe, Mrs Plaistow was almost certain to be visiting the other. Rapidly Miss Mapp remembered that at Mrs Bartlett's bridge-party yesterday Mrs Plaistow had selected soft chocolates for consumption instead of those stuffed with nougat or almonds. That furnished additional evidence for the dentist, for generally you could not get a nougat chocolate at all if Godiva Plaistow had been in the room for more than a minute or two . . . As she crossed the narrow cobbled roadway, with the grass growing luxuriantly between the rounded pebbles, she stumbled and recovered herself with a swift little forward run, and the circular feet twinkled with the rapidity of those of a thrush scudding over the lawn.
By this time Isabel Poppit had advanced as far as the fish shop three doors below the turning down which Mrs Plaistow had vanished. Her prancing progress paused there for a moment, and she waited with one knee highly elevated, like a statue of a curveting horse, before she finally decided to pass on. But she passed no farther than the fruit shop next door, and took the three steps that elevated it from the street in a single prance, with her Roman nose high in the air. Presently she emerged, but with no obvious rotundity like that of a melon projecting from her basket, so that Miss Mapp could see exactly what she had purchased, and went back to the fish shop again. Surely she would not put fish on the top of fruit, and even as Miss Mapp's lucid intelligence rejected this supposition, the true solution struck her. "Ice", she said to herself, and, sure enough, projecting from the top of Miss Poppit's basket when she came out was an angular peak, wrapped up in paper already wet.
Miss Poppit came up the street and Miss Mapp put up her illustrated paper again, with the revolting picture of the Brighton sea-nymphs turned towards the window. Peeping out behind it, she observed that Miss Poppit's basket was apparently oozing with bright venous blood, and felt certain that she had bought redcurrants. That, coupled with the ice, made conjecture complete. She had bought redcurrants slightly damaged (or they would not have oozed so speedily), in order to make that iced redcurrant fool of which she had so freely partaken at Miss Mapp's last bridge-party. That was a very scurvy trick, for iced redcurrant fool was an invention of Miss Mapp's, who, when it was praised, said that she inherited the recipe from her grandmother. But Miss Poppit had evidently entered the lists against Grandmother Mapp, and she had as evidently guessed that quite inferior fruit — fruit that was distinctly "off" — was undetectable when severely iced. Miss Mapp could only hope that the fruit in the basket now bobbing past her window was so much "off" that it had begun to ferment. Fermented redcurrant fool was nasty to the taste, and, if persevered in, disastrous in its effects. General unpopularity might be needed to teach Miss Poppit not to trespass on Grandmamma Mapp's preserves.
Isabel Poppit lived with a flashy and condescending mother just round the corner beyond the gardener's cottage, and opposite the west end of the church. They were comparatively new inhabitants of Tilling, having settled here only two or three years ago, and Tilling had not yet quite ceased to regard them as rather suspicious characters. Suspicion smouldered, though it blazed no longer. They were certainly rich, and Miss
