I thought it was a very interesting story. I like the way it was written.

Alright i read your story and maybe thought i should point a few things that i found glaring...

-From top to toe I have no idea how William, Isabelle or rather any of the characters looked like, nor how the place (or rather the setting of the story) looked like. The only clue I understood was it was from London in 1950s in a posh district for the rich.

-To be honest, I found the plot in it's raw form very interesting. And the twist really was unexpected. But, the twist wasn't handled well...it's like "oh, the murderer is William's fiancee because the script says so".

But the plot is interesting. Plenty of potential. Keep writing! Sorry if my review sounded a little harsh...but guess you kinda expected it right? Just thought i should point a few things out...

but please, keep writing :)
