The Blackmail Letter
Dear Grand Duke Romanov,
I want to congratulate you on your continuous struggle to fight the Soviet Regime. My support is ever-growing.
I believe the explosion of the railroad was a truly magnificent operation. I can guarantee our support hereon.
Letter in the ‘King vs Shelby and Gray’ case file:
(Obscured by photo) are having a garden part at our house in Dorset. I would like to invite you and your wife and family as my special guests. The weather is expected to be very seasonable (i think ti says that). I will be pleased if your family will honour us by letting us entertain you for the weekend. I hope your children are in fine health and please give my best regards to your wife Lady Asimov. I will arrange for you all to be met at the station. I hope this arrangement will be to your satisfaction and I greatly look forward to your arrival.
