Okay. A more thought -out review here.  No smilies etc.. this is serious!

The older man sat at his desk......... lovely start, the feather bed, the quill pen, lone candle. Speaking to another time and place.. and I can tell immediately  that is going to be a tear-jerker. Dare I read on?

It's so sad that Ed still misses Alec,but he goes on to talk about his wife and playing with her and their childre.. as if the old Ed in Shado would ever have been able to do that. And we see that he has changed, has settled, is happy, even though he misses ALec's grin.
 
A houseful of children; another reminder that this is a different Ed, relaxed, happy, content. Life has been good to him, here. And as he thinks back over the years at HQ, the sad times, we see again how happy he is, how much joy his life contains. A wife; irresistible, baby daighters, young sons; and to have found peace at last.... lovely.

I like the way he is still thinking about Shado, and Jake, and Keith. But it is no longer the focus of his life. he has other things to keep him busy now..a son who is ten.. loved the reference to John,and Ed's reference to calling his son Alec.

It's sad that he acknowledges that Alec will never read the letters, (but you never know...! I have my own private thought that Alec will get the letters one day!) and I'm glad he mentions the painting.
Lovely that he mentions the aliens and how he is still battling them, and teaching his family to fight them.. a new generation of Straker's in the fight!

And the final paragraph.. a father again.. 'Happy with the fate that time has brought me.'     perfect.

As is the dedication at the end.

Ever your friend

A gloriously triumphant letter.
Thankyou.
Louise

I think I'd like to see it almost as a 'non-chapter/epilogue.
 
just put  on the end for the reader to find .. as hopefully Alec does!

No title, no message.

It doesn't really need any thing else to be said.

I just added the last two episodes of the Devilsgate Saga to my website.  (Although the 6th story isn't really story length, I still included it under its own name and number.)  Oh, and Matt, I changed the title to fit with the rest of the saga.
Louise, I used that wonderful painting I found online of Strawberry Hill for the 6th story pic on my site.  It turned out great.  Looking through the pics for this saga, I find that I used Ginny a lot.  But unfortunately, I don't have a pic of Jake!
I'll get them up on fanfiction soon.  Thanks for the lovely feedback as I've been writing these!  I bloom with encouragement.
