Don Carter resigns from the police force and becomes a private detective. He's good at his craft and his business grows. This is a different type of story for me.
By age 18 I was an electronic and computer genius. At that time I invented a small gadget that when attached the right way to a phone extension, you could listen in on any call on the other extensions without the infamous 'click' that was a giveaway. I could connect the device to my computer, have the calls recorded and listen to them at any time.
