Dear former owner of this key,
I found it in the river. Who knows, maybe you thought that as previously, this was a secure method of destruction. Or else it was dropped accidentally or on purpose. Oops.
Unfortunately the key has now been stolen, in mysterious circumstances, from what I thought was a suitably secure location. Even more oops.
Dear mystery,
Would you like to explain wtf that's about, either in public or by PM? And maybe give my boat back, because I hate making boats.
[The theft appears to have been limited to three master keys, including the one for the property where the theft occurred, and maybe a flotsam but tbh I might have studied that when I wasn't looking. It's not like there was much of value there, I suppose.]
