Please Read Carefully

by Adem Karadag

Good day. I got your contact from an online European business directory as a reputable industrialist with high integrity. I have a proposition that I think will be of great interest to you. I am the personal assistant to the son in- law of a Russian businessman. My boss and his father in-law and part of the few top official in the inncer circle of the current cabinet that strongly opposes the war in Ukraine. They have been frustrated by the sanctions and poverty level that the country has fallen into ever since the war began. The only problem is that it is impossible to oppose the President publicly because those that have attempted to do that in the past were killed. That is why these small group of oppoistion are trying to secure their assets both home and abroad to avoid it being seized. The main reason why I am contacting you today is to propose a business cooperation that will be of mutual benefit to both of us and requiring absolute trust and total confidentiality. To get down to brass tacks, we need you to accommodate a large volume of assets for safekeeping. Bear in mind that these asset is aready safely out of the Russian country and was secured by a proxy so you are not at any risk of jeopardizing your safety at all. We need an established businessman or owner of a big company or industry for this task, and you will be handsomely rewarded for your efforts as well. If you are interested in this proposition, kindly respond back to me so I can give you further details and what is required for our trust. We will also negotiate an appropriate compensation for your efforts. Yours faithfully Adem Karadag.
