“We broke down – as I had expected – and had to lie up for repairs at the head of an island. This delay was the first thing that shook Kurtz’s confidence. One morning he gave me a packet of papers and a photograph – the lot tied together with a shoe-string. ‘Keep this for me,’ he said. ‘This noxious fool’ (meaning the manager) ‘is capable of prying into my boxes when I am not looking.’ In the afternoon I saw him.
