“Can you say it again?” said Henry. “I’d like to get it down in black and white, and have a look at it. At present it makes me feel giddy.”

“You mustn’t write it down,” said Jane breathlessly. “Oh, you mustn’t, Henry! It’s not safe.”

Henry turned on his torch, propped it against the wall, and produced a notebook and a pencil. The cold, narrow beam of light showed his knee, the white paper, a pencil with a silver ring, and Henry’s large, brown hand.

Jane picked up the notebook, stared at the written words, set Henry’s facts in the forefront of her mind, and remarked candidly:
