I believe the novel "The Word" by Irving Wallace (1972) features something similar, if I remember correctly.

- eesmith 4y agoFound it! https://archive.org/details/word0000wall/page/336/mode/2up https://archive.org/details/word0000wall/page/336/mode/2up > "... Say we send this memo to the same people who received the other memo — well, we don’t have to include anyone in this room — you’re in on it — but we’ll send copies to every one of the others. Each copy of the new memo would be exactly the same, except for one word. In each memo there would be one word not in the others. We would keep a record of the person to whom we sent the memo — and beside his name we would jot the unique word that was in his memo. Do you see what I’m driving at? When the memo goes out, the person here who is betraying us will pass it on word for word to de Vroome, isn’t that so? Your informer in de Vroome’s headquarters would learn of it and report back to you. Since no memorandum would be precisely the same as the others, because of the single word change, you’d look for the different word in the memo de Vroome received and be able to find out the person who had passed on his copy of the memo. You'd know your traitor."
