The Three Cities Trilogy: Paris

Then the Chief of the Detective Force told the whole story: how Detective Mondesir, on being warned by a secret agent that the Anarchist Salvat was in a tavern at Montmartre, had reached it just as the bird had flown; then how chance had again set him in presence of Salvat at a hundred paces or so from the tavern, the rascal having foolishly loitered there to watch the establishment; and afterwards how Salvat had been stealthily shadowed in the hope that they might catch him in his hiding-place with his accomplices.
