From the Father Brown story "The Blue Cross":

It was he who had kept up an unaccountable and close correspondence with a young lady whose whole letter-bag was intercepted, by the extraordinary trick of photographing his messages infinitesimally small upon the slides of a microscope.

What is the "trick" being described here? I don't understand what it is or how it works.

He made very, very, very small letters, on microscope slides. These were sent to the young lady in question, who used a microscope to read them.

  • Thank you. I didn't get that the recipient of the micro-messages was the young lady (I thought that the unaccountability was paart of the trick, not the result.) – Kyle Johansen Apr 3 at 8:09

"The Blue Cross" was the first Father Brown story, published (according to Wikipedia) in 1910.

The technology of photo microdots had been known for some decades by then.

    Could you explain what photo microdots are, and how they relate to the story? We prefer answers to be self-contained. – bobble Mar 26 at 19:53
