The season 2 episode To the Last Man gave us in flashback a glimpse at the Torchwood of WWI, and I kept hoping this would inspire fanfic. Now it has, and great fanfiction, too. Here it is, with an excellent sense of period and plausible degree of TW-inherent messed-up-ness:

On a lighthearted note, Gwen's honeymoon, which must have happened between Something Borrowed and Out from the Rain, is another gift to fanfic.

The rest of you can have Jack and Ianto.) (But not Owen/his issues. That's my other TW OTP.) Read and enjoy:
