The first came by post and was a pamphlet on _ Christian Science and Absent-Mindedness _ , exactly similar to the one I had taken away from the old curiosity shop ; the second was a small key made from my wax impression that would fit the front door of the same shop -- a key fashioned by an excellent anarchist friend of mine in an obscure street near Holborn . That night at ten o'clock I was inside the old curiosity shop , with a small storage battery in my pocket , and a little electric glow-lamp at my buttonhole , a most useful instrument for either burglar or detective . I had expected to find the books of the establishment in a safe , which , if it was similar to the one in Park Lane , I was prepared to open with the false keys in my possession or to take an impression of the keyhole and trust to my anarchist friend for the rest . But to my amazement I discovered all the papers pertaining to the concern in a desk which was not even locked .
