Nick held the large glass and the photograph so that all three could plainly view the magnified picture.
“I’ll explain what I find, and I wonder that I have not noticed it before,” said he quite earnestly. “It relates to this tall woman who appears in the picture.”
“Gee! but she is a tall one,” remarked Patsy, with a laugh. “She’s tall enough to fit in a dime museum.”
“That’s right, Patsy,” assented Nick, smiling.
“What’s peculiar about it, Nick?”
“As you probably know, Chick, there is a general uniformity in the proportions of the human body—a regular length of arms and limbs when compared with the trunk. In all normal subjects the proportions are nearly the same.”
“Sure,” nodded Chick. “A man’s reach, from the tips of his extended arms and fingers, is usually the same as his height.”
“Correct.”
“But what has that to do with the picture, Mr. Carter?” asked Patsy.
“It has to do with this woman,” Nick rejoined, drawing out his pencil to be used for a pointer. “I want you to notice her extended arm and hand, the one in which she held the leveled revolver.”
