Paul Cornell's "One of our Bastards is Missing" (novelette, detective, free): Prussians don't want British princess to marry Swedish prince

Fast paced action story, but with magic - space-time "folds" used as caves & nooks. While the magic doesn't really come in the way of the story, it made me feel the mechanics of mystery was gamed.

Story summary.

A wedding in London - British princess marrying Swede prince. Amid all the merriment, there is a curious incident: a man vanishes into thin air in front of the whole crowd!

Major Hamilton will unravel the mystery, & major international intrigue...
