You can't act death. The fact of it has nothing to do with seeing it happen - it's not gasps and blood and falling about - that isn't what makes it death. It's just a man failing to reappear, that's all. Now you see him, now you don't. That's the only thing that's real: here one minute and gone the next and never coming back - an exit, unobtrusive and unannounced, a disappearance gathering weight as it goes on, until, finally, it is heavy with death.
