Crefton slipped quietly away, uncertain whether or no the old woman had noticed his presence. Even before she had proclaimed the guiltiness of Betsy Croot, the latter’s muttered incantation “Let un sink as swims” had flashed uncomfortably across his mind. But it was the final threat of a retaliatory spell which crowded his mind with misgiving to the exclusion of all other thoughts or fancies. His reasoning powers could no longer afford to dismiss these old-wives’ threats as empty bickerings. The household at Mowsle Barton lay under the displeasure of a vindictive old woman who seemed able to materialize her personal spites in a very practical fashion, and there was no saying what form her revenge for three drowned ducks might not take. As a member of the household Crefton might find himself involved in some general and highly disagreeable visitation of Martha Pillamon’s wrath. Of course he knew that he was giving way to absurd fancies, but the behaviour of the spirit-lamp kettle and the subsequent scene at the pond had considerably unnerved him. And the vagueness of his alarm added to its terrors; when once you have taken the Impossible into your calculations its possibilities become practically limitless.
