In fact

In fact is a discourse marker.

We use in fact to add more detailed information to what has just been said:

A:
Did she pass her driving test?

B:
Yes, she did;in fact, she’s now taking an advanced driving test.

In fact is commonly used in front position in a clause, although in informal situations, it may occur in end position:

The holiday was really disappointing – a complete disaster, in fact. It just rained all the time.

Other discourse markers which have similar meanings include: in actual fact, as a matter of fact, in point of fact, actually, in truth.
