Mr. X monologue (Act 3) — Plays by August Strindberg, Second series

I see in the mirror that you are a thief--a plain, ordinary thief! A moment ago, while you had only the white shirt on, I could notice that there was something wrong about my book-shelf. I couldn't make out just what it was, for I had to listen to you and watch you. But as my antipathy increased, my vision became more acute. And now, with your black coat to furnish the needed color contrast For the red back of the book, which before couldn't be seen against the red of your suspenders--now I see that you have been reading about forgeries in Bernheim's work on mental suggestion--for you turned the book upside-down in putting it back. So even that story of yours was stolen! For tins reason I think myself entitled to conclude that your crime must have been prompted by need, or by mere love of pleasure.
