Corrected. I'm not quite awake and on my game in the initials department, after a week of the flu.
Maple Gate may have been a primary residence - but it would appear so far in the chronology of events, that it was serving as little more than a mail-drop, in the days immediately after TB's murder.
I think the mail drop inference came mainly from the press after the place was searched by police IIRC. This would have been sometime after May 9th I think.
