“I believe you!' the artiste exclaimed finally and extinguishes his gaze. 'I do! These eyes are not lying! How many times have I told you that your basic error consists in underestimating the significance of the human eye. Understand that the tongue can conceal the truth, but the eyes - never! A sudden question is put to you, you don't even flinch, in one second you get hold of yourself and know what you must say to conceal the truth, and you speak quite convincingly, and not a wrinkle on your face moves, but - alas - the truth which the question stirs up from the bottom of your soul leaps momentarily into your eyes, and it's all over! They see it, and you're caught!”

“The tongue can conceal the truth, but the eyes never! You're asked an unexpected question, you don't even flinch, it takes just a second to get yourself under control, you know just what you have to say to hide the truth, and you speak very convincingly, and nothing in your face twitches to give you away. But the truth, alas, has been disturbed by the question, and it rises up from the depths of your soul to flicker in your eyes and all is lost.”
