What the clue says
The first half is a room clue: the person was in the named room. The second half is a count. "With another man" means exactly one man besides the person was in that room, never two. Women may also have been there, any number of them. "With another woman" works the same way the other way round.
How the game words it
- MateoHe was in the Study with another man.
- AlmaShe was in the Kitchen with another woman.
What it rules out
For the person, every cell outside the room. For the others, it sets the count. If one other man is already placed in the Study, no third man can enter it. If no man is there yet and only one man can still reach the Study, that man must be there. Women are not counted, so they come and go freely.

Is there a negative form?
No. The game has no "without another man" clue. For a room nobody else was in, the clue is alone in the room.
Common mistakes
- Counting the speaker. "Another man" means one man besides him.
- Reading it as "at least one". It is exactly one. A third man in the room breaks it.
- Keeping women out. The count is only about the named gender.
- Forgetting the room. The clue places the person in that room too.
How it combines with other clues
Treat it as a room clue first: cross out every cell outside the room. Then count who can still reach the room. If the room is the victim's, it holds exactly two people, so the other man is either the victim or the killer. Most of the work here is counting, and the technique room counting shows the steps. Pair it with line clues to find which cell of the room is free.
