My daughter has recently moved into a 1930s semi and, after a few weeks,
is finding that one of the bedrooms smells strongly of tobacco smoke in
the mornings. No one in the house smokes and it's presumed that it's
coming from next door. Obvious possibilities a through the window -
unlikely? through blocked up flue; through hidden air vent ?

My guess would be poor mortar work in the party wall behind the skirting
or in the floor void beneath.
