William Le Queux,
The Czar's Spy — Chapter 4: In Which the Mystery Increases
(1905)
“ Half an hour later my uncle's carriage was announced, and I left with the distinct impression that there was some deep mystery surrounding the Leithcourts. What it was, however, I could not, for the life of me, make out. Perhaps it was Philip Leithcourt's intimate relation with the man who had so cleverly deceived me that incited my curiosity concerning him; perhaps it was that mysterious intuition, that curious presage of evil that sometimes comes to a man as warning of impending peril. ”
