eight o'clock in the morning
`` I told you I had an eye on you . It was the lone eye of the camera . And on Sunday it kept watch for us here , winking every ten minutes . From eight o'clock in the morning to three in the afternoon it winked forty-two times , and all it saw was the same scene , the empty corner of the room here , with the safe in the shadow at first and at last in the full light that poured down from the glass roof over us . But a little after three a man came into the office and made ready to open the safe . At ten minutes past three the clock and the camera took his photograph -- in the twinkling of an eye . At twenty minutes past three a second record was made .
