Damp problem, to middle of inside of Bay on Victorian Terrace- Cause?

I have a damp problem on the inside wall adjacent to bay on ground floor front room of victorian terraced house. The damp area is approximate 50-60cm squared and begins around 1m up from the wall and stretches from the bay window across to the inside wall. The damp area is mirrored on the outside of the building, where the bricks and mortar appear damp, even when not raining. The area that is damp on the outside has been repointed/repaired at some point in recent yeats (i moved in 6 months ago, so before then) and I wonder if it could be the pointing itself that might be soaking up water and spreading into bricks, which then affects the plaster. I have checked the guttering on both the single bay and from the roof and there doesnt seem to be any direct exposure to water from here. There is a damp proof course in the cellar and it appears the lower half of the front bay has been replastered- possibly as a result of a previous rising damp problem, so I dont think rising damp is the cause of the current issue. I cannot see any obvious area where water could be penetrating. Any ideas of the cause? Could the pointing itself be the culprit?
