The mysterious M (who may or may not be associated with British Intelligence) was obviously on an undercover mission in Chicago when s/he signed up for the exchange! In the middle of his/her 'studies' (nice cover, M), my Santa found the time to write this card and mail it out to me.

M apologised that it wasn't exactly what I was looking for, but being a spy, I know M has hidden some sort of secret code in the message or baubles so I can understand exactly why s/he chose it. Also it's very pretty, which I know will throw off M's enemies had they intercepted this top secret Christmas card on its way here.

M wished me a prosperous 2016 which I think means s/he hopes I will succeed in my next mission as I infiltrate my in-law's on Christmas Eve and try to detect who is fiendishly plotting to eat all of the stuffing and roast potatoes.

I only hope that the card doesn't explode now that I'm done reading i-

BOOM
