Confession of a Dangerous Mind

This could also be a good way to help our filming techniques. How the camera focuses on him, allowing the audience to realise that something isn't right. This builds tension in the audience because the audience knows that he he been poisoned  But we thought that if we took inspiration from the Sherlock Holmes scene, where we haven't seen the cook poison his food, until he has a flashback type thing. We could make it so that, like in this, the man begins to realise somethings wrong, and the audience then also like him,  do not know what is going on,this could build confusion and suspense in the audience until it is revealed that the man has been poisoned.
Then from the close up of his realisation, through his slow suffering, having the cook,in her placement, over the shoulder, blurred into the background, but is still visible.I think this would be a good camera technique because it suggests that the cook did it, if the audience didn't already know,and created a more visually interesting screen, because it is setting up the rest of the film in the audiences minds, that the cook has a main part to play.
