My original musing for this page:
This off-the-wall idea would involve at least two major stories: the first, to set things up in the world of The Wild Wild West; the second, to send those characters to the present day and encounter the cast of Perry Mason. It could conceivably be a trilogy, but I have a very bad knack for losing steam during the third installments of almost all trilogies I've tried to write. I think I only ever completed one trilogy, out of several I started. Therefore, a duology is a safer estimate for now. Although perhaps, Resurrection would be short and more of a prologue, with Time Travel as the only really big story.
Now, I have not only managed to write a trilogy, I have an idea for a fourth installment.
