I enjoyed it though I could do without Dorothy as well - can't Siegfried just get together with Mrs Hall? I wonder if some of what they included may have been drawn from life - e.g. I believe Siegfried was actually a young widower, which isn't in the books, and James did apparently have a slightly strained relationship with his own parents, who don't appear at all in the books.
Helen does have another friend/boyfriend in the stories though, Richard, who is a well off family friend who her dad initially prefers to James.
Captain I've recently reread all the stories to my DS having loved them as a child and certainly have seen all the drink driving, drunk vetting and general drinking with fresh eyes! He adores them though and they have become his comfort stories in lockdown.
