tsarevich's diaries

[Serge Rogosin]

Does anyone know if there are any diaries or letters written by Alexei, the
last tsarevich,  that survive?  What archives would they be in? Has anything
like that ever been published? Nicholas's and Alexandra's letters mention
Alexei writing letters to his father, but I've never seen any other
references.

Is anyone aware of any biographical works on Alexei specifically?

Any information would be much appreciated.

Serge
