Great acting, great twists, great story, nothing to add to that. However I was bit baffled by the sub-plot of the copper... this could have been developed a bit more, as as it is now, this guy chasing 50-year old murders does not make much sense.
Also for those wondering about the Solange actress swap, well, clearly it's because the first "Solange" is a creation of Adrien's mind; it is said at the beginning, Albert does not have any photo of her so what she looks like is left to Adrien's imagination. Later on, when who Solange really is is revealed, it is then possible to put a proper face on the character. So it's no mistake or fault!
