"Flesh and blood can't disappear in a second!"
"It's most uncanny!"
"The old Cistercians wore white habits."
"I say, I don't like this!"
Brother Lawrence, as the girls began to call the apparition, showed himself frequently, but always with the same elusiveness. The phenomenon was invariably as before: his white monastic robes would glimmer through the darkness, glide up the stairway, and then seemingly melt into nothing. Geraldine herself pursuing hotly on the scent, found that she was utterly baffled.
A head girl, especially a prefect with a scorn for superstition, does not like to admit herself baffled. Geraldine thought the matter over, took Loveday into her confidence, and went to Miss Todd. As the result of her interview she resolved to set what she called "a very neat little spook-trap". She and Loveday said nothing about it to the rest of the school. They merely bided their time.
Brother Lawrence did not always show up when anybody was on the watch for him; he seemed to prefer displaying his supernatural powers to the unwary. For two whole days he did not put in an appearance; whether he was haunting elsewhere or expiating his sins in purgatory was a point for discussion. On the third evening, however, Tattie, Jess, and Magsie had screwed their courage to sticking-point, and strolled upstairs in the twilight, half hoping and half fearing to catch a glimpse of the now almost familiar apparition. They kept in the shadow of the big cupboard, and held each others' hands without speaking. A full moon was shining through the landing window, and lit up the narrow staircase with a silvery, ghostly gleam. Suddenly from the darkness of a doorway emerged the white robes, and passed rapidly upwards in the moonlight. Still clutching hands for moral support, the three girls tore after it. Surely this time they could manage to overtake it? But no; it had turned the corner before they reached the lowest stair, and by the time they had dashed up the ten steps it had made its usual disappearance. They halted on the yard of landing, breathing hard; then their hearts seemed to turn somersaults, for the attic door suddenly opened. It was no ghost who peered forth at them, but Geraldine and Loveday. The former had a candle in her hand; she struck a match and lighted it calmly.
"You needn't look so scared!" she said to the panting trio. "I'm just going to show you your precious spook. Stand back a little, will you? I assure you it won't bite you!"
She descended to the landing, turned round towards the four steps that led to the attic door, then, to the immense amazement of the girls, raised up the steps like the lid of a chest. There was a good-sized cavity below, and in this place of concealment crouched a white-clad figure. Geraldine took it by the arm and hauled it unceremoniously forth. It issued chuckling, and, as its cowl fell back, disclosed a well-known and decidedly mirthful countenance.
"Stars and Stripes!" ejaculated Jess.
