The story of Margaret Atwood's Alias Grace is built up on letters, newspaper accounts of the trial, third person view - the narrative of the fictional Dr. Simon Jordan, and mostly on Grace's own memories stretching as far as her impoverished childhood in Ireland and the traumatic journey to Canada. But what is memory? Who does it belong to? Is it inseparably bound with the storyteller or with the actors told about? Or perhaps it is entirely constructed by the listener? Whatever the case, can we trust it? Is it real - the truth? In my essay I will try to find out the plausibility of truth - if there is one and whether it can be proven when based on written historical accounts and memories. I will try to see which is real and which is made up. Or at least prove that this aim is not possible to achieve. I will revise Alias Grace and its literary criticism.
