“You are certainly a model client. You have the correct intuition. Let us see, now.” He spread out the papers upon the table, and gave little darting glances from one to the other. “They are disguised hands, except the letter,” he said, presently, “but there can be no question as to the authorship. See how the irrepressible Greek _e_ will break out, and see the twirl of the final _s_. They are undoubtedly by the same person. I should not like to suggest false hopes, Miss Morstan, but is there any resemblance between this hand and that of your father?” “Nothing could be more unlike.” “I expected to hear you say so. We shall look out for you, then, at six. Pray allow me to keep the papers. I may look into the matter before then. It is only half-past three. _Au revoir_, then.” “_Au revoir_,” said our visitor, and, with a bright, kindly glance from one to the other of us, she replaced her pearl-box in her bosom and hurried away. Standing at the window, I watched her walking briskly down the street, until the grey turban and white feather were but a speck in the sombre crowd. “What a very attractive woman!” I exclaimed, turning to my companion. He had lit his pipe again, and was leaning back with drooping eyelids. “Is she?” he said, languidly. “I did not observe.” “You really are an automaton,—a calculating-machine!” I cried. “There is something positively inhuman in you at times.” He smiled gently. “It is of the first importance,” he said, “not to allow your judgment to be biased by personal qualities. A client is to me a mere unit,—a factor in a problem. The emotional qualities are antagonistic to clear reasoning. I assure you that the most winning woman I ever knew was hanged for poisoning three little children for their insurance-money, and the most repellant man of my acquaintance is a philanthropist who has spent nearly a quarter of a million upon the London poor.” “In this case, however—” “I never make exceptions. An exception disproves the rule. Have you ever had occasion to study character in handwriting? What do you make of this fellow’s scribble?” “It is legible and regular,” I answered. “A man of business habits and some force of character.” Holmes shook his head. “Look at his long letters,” he said. “They hardly rise above the common herd. That _d_ might be an _a_, and that _l_ an _e_. Men of character always differentiate their long letters, however illegibly they may write. There is vacillation in his _k_’s and self-esteem in his capitals. I am going out now. I have some few references to make. Let me recommend this book,—one of the most remarkable ever penned. It is Winwood Reade’s ‘Martyrdom of Man.’ I shall be back in an hour.”
