As in the blog Missing days , I mentioned the English saying, To Smell a Rat.
The saying smell a rat means that there is something wrong, something is not right.
It could mean that someone is going to set a trap on another person into doing something that they do not want to do, to manipulate them into doing something or an carry out an action which is wrong.
Perhaps the onlooker or recipiant does not know what is going to possibly happen, but intuition tells them to be aware.
