Мне дан абзац :
My mind was now racing. I had to find Bert, get hold of Kurt Klassens again, check
my suspicions. But first, I had to try to overhear as much of their
conversation as possible. It wasn't easy. Several of them were talking at once.
There was a noise of plates and knives and forks. All I could hear were bits
and pieces of what they said, 'What are we going to do now then?', 'How come
you didn't take care of this back in Bambacocha?', 'Where is he now?', 'What do
you mean, you don't know? We have to know!', 'Maybe he hasn't made the connection.
Maybe we're worrying about nothing.', 'What happened to the girl?', 'We can't
afford any more mistakes, Strang. Your head is on the block - and so is mine if
this gets out...'
Я не могу перевести такие предложения :1) How come you didn't take care of this back in Bambacocha?
2)Your head is on the block - and so is mine if this gets out...
3)Так же не могу перевести слово "Bambacocha"
Помогите, чем можете. Спасибо.

1)Как так получилось, что вы еще не позаботились об этом в Бамбакоча?2)Твоя голова на плаху и так принадлежит мне, если это выйдет ... "Bambacocha" - это и есть Бамбакоча, возможно это название чего-либо.
