His demise is his end, so "Would this be where the inevitable demise of a turmoiled Sam met his end" doesn't actually make sense.
"Would this be where Sam met his demise?" or "would this be where Sam met his end?" would make sense. To write noirish stuff well put down the Patterson and pick up some Chandler.
On the same note, and sadly accepting that I'll probably be writing much less interesting things than a novel for the foreseeable... is it possible to work using dropbox as if it were a local folder? That is can I open a doc in my dropbox folder on my Note 10.1, work on it, save it, and then pick it up on another device via dropbox as well? So far I've not worked this out but it would be the most seamless way for me to work the way I'd like to.
