DearJohn,
    Many thanks for your letter which came yesterday. It took a month. I am now sending another invitation as requested. I shall try and send this to you by personal courier in view of the postal problems.
    I wonder when your are thinking of coming to Moscow . In some ways September would suit me best, as I have to be away most of the month and would like to have a «watchdog» in the house. But please arrange things as it suits you best.
    With best wishes.
    Yours very sincerely,
