I think it needs to be pointed out that "Dark Passages" is NOT Kathryn Leigh Scott's first work of fiction, "Murder In Prime Time" was. I think it came out in 2006. I seen this mistake made by more than one writer.
I do hope the cameos don't wind up on the cutting room floor, but it could easily happen.
All the stuff about the Cannery and the harbor is quite fascinating! I always wondered whether there was a lingering odor of canned sardines at Collinwood. One would imagine they would have been a staple of the meals there.
