My other theory was that the kobold injured his wife, then he went down to the carp filled river to get her some water. However, then it would have had the interrupted by carp message, and I couldn't find his body in the river.
It's a lot easier than that. The recordkeeper was simply a kobold in disguise, finally throwing of his cloak because in his daily routine the only thing he could steal was food. In a fit of rage he tried to kill the foul women he was forced to marry with. It all makes sense now!
On topic, I got this relatively well-faring fortress, just got my 200th dwarf, everything is going fine.
Then a Goblin siege comes by, I deploy my usual routine of ordering everyone inside and lowering the main gate to let the goblins crawl through my terribly long trap back-entrance filled with whips flails and obsidian sowrds. However noone comes to pull the lever. The goblin army advances steadily towards my gates, while everyone is to busy eating, sleeping, drinking, partying, and getting set on fire because the magma pipe was the fastest way to the booze...
In a desperate attempt to delay the inevetible I set out my entire poorly trained and poorly equiped military. To my suprise they marginally defeat the goblin hordes, with a total of 5 survivors, of which 2 bleed to death just seconds after the goblins left. The remaining 3 stumble back to the barracks, one of which had both arms cut, another had his right leg cut of, and a third was missing his left eye and kidney
Besides that they both had numerous yellow or red injuries.
At the exact moment they cross the main bridge, on which I stationed my mayor and some legendary dwarves to congratulate the now elite/hero's some idiot (I think it was the philosopher) is suddenly reminded of the fact that the lever behind the main bridge still needs pulling....
Even more unfortunate I had rerouted my underground river filled with bloodthirsty pike under the bridge. The entire river run red with blood
(well atleast for about 20-30 squares)
This fort eventually died of a massive tantrum spiral because everyone lost friends due to either the massive slaughter by the goblins, or that by the pike's shortly thereafter.
