Unknown

When everything has been taken from you . . .

There's nothing left to lose.

Martin Harris has been in a coma for three days.

When he wakes up, otherwise unharmed, he is shocked to discover that no one knows who he is - he no longer exists.

Worse still, another man is living Martin's life. His identity, his home, even his wife have been stolen. He has lost everything.

Except his memory . . .

Will anyone believe that he is the real Martin Harris?

If not, is he mad?

Or is there a far darker explanation?
