I just wanted to apologize for the delay in part 3 of "Between one step and the next". I felt like I had written myself into a corner, and was about to despair, but I think I see a way out now. Unfortunately, with real life being what it is at the moment, my writing time is seriously curtailed, so it will take a bit. It will come when it does, so thank you for your patience. and again, my apologies.
