At last he found out the truth.

Do the above three all sound right? If yes, do they mean about the same thing? Thanks.

At last he found out the truth. He is made aware about the truth - probably not a nice one: "At last he found out the truth - his wife had been having an affair".

At last he found the truth.
At last he discovered the truth.

Both of these can say substantially the same, though "discover" rather leaves an impression of sudden revelation.

Did you have a context in which they are to be used?
