On a table in the living room, Tina - not her real name - has made a display with tealights, pastel-coloured eggs, candles and a little wooden cross. It's her own, intimate way to mark Easter.
She and her husband converted to Christianity years ago, something that in their country, Iran, is forbidden by law.
They could be arrested at any time.
The Iranian constitution recognises a few religious minorities. Armenian and Assyrian Christians can practise their religion, but they are banned from preaching to other Iranians or even letting them into their churches.
