John Watson was an army doctor with a history. An assistant surgeon, serving in Afghanistan, with the regiment of the Fifth Northumberland Fusiliers, he was strong, brave, a little impatient perhaps, but altogether an appropriate soldier, serving his King and Country.

No more 'strong and brave' on an army pension in London.

But it turns out that your presence in this world is even bigger deal than you first thought, and soon, everyone wants to make you theirs.
