[John] - You pretended to be dead for two years!
[Sherlock] - Apart from that!

Last days Sherlock was called a liar many times, but is he really?
He is manipulative, deliberately misleads people, using his clothing, posture, or behavior. He can suggest something, using implicit statements, or simply not mentioning some points. But he uses this tricks mostly to solve murders. When he's got the necessary information, (or effect, like John's forgiveness in TEH), he lets his interlocutors to know the truth. His lies are sometimes irritating, but used mostly to get the answers faster, and harmful only to the criminals.
Does it really count?
