Deciphering Secret Correspondence: MİT Archives Reveal Method

The National Intelligence Organization (MİT) has shared a historical document regarding the deciphering of secret correspondence. The document, dated 1933, outlines the chemical substances and methods used for deciphering secret writings. A new addition to the 'special collections' section of MİT's official website, the document includes an example of the Technical Support Division's activities in opening and deciphering secret letters sent to the Istanbul B Directorate. The document states that the envelope in question was opened using a specific method and notes that the first page of the letter was partially damaged due to experimentation. The translation of the legible parts of the letter and the second page are attached. The letter bears the signature 'Lüsi', leading to speculation that the sender may be Lucci Vidman. For any future letters from this source requiring chemical treatment, the following formula is recommended.
