Harry Horse and The Magic Microdot

Harry Horse, Private Detective, slowly and very deliberately read the ransom note again that had just been delivered by messenger and wondered why it had been sent to him because he didn't have any friends, or relatives, that had been kidnapped recently or for that matter at any other time but if they had been where on earth was he supposed to get that amount of cash from and that's when his inner thoughts, brain box, memory and panic, had their say.
