On an investigative trip into a dense Welsh forest in which a particularly vicious Boggart was supposed to be lurking, Lyall ran across his future wife. Hope Howell, a beautiful Muggle girl who worked in an insurance office in Cardiff, had taken an ill-advised walk through what she believed to be innocent woodland. Boggarts and poltergeists may be sensed by Muggles, and Hope, a particularly imaginative and sensitive person, had become convinced that something was watching her from between the dark trees. Eventually, her imagination became so overactive that the Boggart assumed a form: that of a large, evil-looking man, bearing down on her with a snarl and outstretched hands in the gloom. Hearing her scream, young Lyall came sprinting through the trees, causing the apparition to shrink into a field mushroom with one wave of his wand. The terrified Hope thought, in her confusion, that he had driven her would-be attacker away, and his first words to her – ‘it’s all right, it was only a Boggart’ – made no impression on her. Noticing how very beautiful she was, Lyall made the wise decision not to talk about Boggarts any more, but instead agreed that the man had been very big and scary, and that the only sensible thing to do was for him to accompany Hope home to protect her.
