A Descent into Egypt by Algernon Blackwood

It was in the windless days of a perfect December that Moleson, the Egyptologist, found us out and paid a flying visit to Helouan. His duties took him up and down the land, but his time seemed largely at his own disposal. He lingered on. His coming introduced a new element I was not quite able to estimate; though, speaking generally, the effect of his presence upon my companion was to emphasise the latter's alteration. It underlined the change, and drew attention to it. The new arrival, I gathered, was not altogether welcome. 'I should never have expected to find you "here",' laughed Moleson when they met, and whether he referred to Helouan or to the hotel was not quite clear. I got the impression he meant both; I remembered my fancy that it was a good hotel to hide in. George Isley had betrayed a slight involuntary start when the visiting card was brought to him at tea-time.

I think he had wished to escape from his former co-worker. Moleson had found him out. 'I heard you had a friend with you and were contemplating further exper work,' he added. He changed the word 'experiment' quickly to the other.
