about
ten o’clock
Yet its contents were startling enough , and this letter she did not read to Katherine Kempt , but bore its anxiety alone . DEAR MISS AMHURST : I write you in great trouble of mind , not trusting this letter to the Russian post-office , but sending it by an English captain to be posted in London . Two days ago Jack Lamont disappeared ; a disappearance as complete as if he had never existed . The night before last , about ten o'clock , I thought I heard him come into his shop below my room . Sometimes he works there till daylight , and as , when absorbed in his experiments , he does not relish interruptions , even from me , I go on with my reading until he comes upstairs . Toward eleven o'clock I thought I heard slight sounds of a scuffle , and a smothered cry . I called out to him , but received no answer .
