“What do you think of it?”

“It’s on the level,” said Nick. “The woman means what she says.”

“Woman?” questioned Mallory quickly. “How do you know a woman wrote it? It isn’t signed.”

“True.”

“And the writing looks like a man’s?”

“True again.”

“Why do you think, then, that a woman wrote it?”

“Sentiment,” said Nick tersely. “It appears between the lines, illiterate though they are. We very seldom find it in men of the class in which the writer of this evidently falls.”

“A fallen class, evidently,” remarked Detective Vallon.

“Possibly,” Nick allowed. “She has a high opinion of you, Mallory, all the same. Very properly too.”
