IV
A STRATAGEM
When the maitre-d'hôtel had shown him all over the establishment (innocently enough, en route, furnishing him with a complete list of his other guests and their rooms: memoranda readily registered by a retentive memory) Lanyard chose the bed-chamber next that occupied by Roddy, in the second storey.
The consideration influencing this selection was—of course—that, so situated, he would be in position not only to keep an eye on the man from Scotland Yard but also to determine whether or no Roddy were disposed to keep an eye on him.
In those days Lanyard's faith in himself was a beautiful thing. He could not have enjoyed the immunity ascribed to the Lone Wolf as long as he had without gaining a power of sturdy self-confidence in addition to a certain amount of temperate contempt for spies of the law and all their ways.
Against the peril inherent in this last, however, he was self-warned, esteeming it the most fatal chink in the armour of the lawbreaker, this disposition to underestimate the acumen of the police: far too many promising young adventurers like himself were annually laid by the heels in that snare of their own infatuate weaving. The mouse has every right, if he likes, to despise the cat for a heavy-handed and bloodthirsty beast, lacking wit and imagination, a creature of simple force-majeure; but that mouse will not advisedly swagger in cat-haunted territory; a blow of the paw is, when all's said and done, a blow of the paw—something to numb the wits of the wiliest mouse.
Considering Roddy, he believed it to be impossible to gauge the limitations of that essentially British intelligence—something as self-contained as a London flat. One thing only was certain: Roddy didn't always think in terms of beef and Bass; he was nobody's facile fool; he could make a shrewd inference as well as strike a shrewd blow.
Reviewing the scene in the restaurant, Lanyard felt measurably warranted in assuming not only that Roddy was interested in De Morbihan, but that the Frenchman was well aware of that interest. And he resented sincerely his inability to feel as confident that the Count, with his gossip about the Lone Wolf, had been merely seeking to divert Roddy's interest to putatively larger game. It was just possible that De Morbihan's identification of Lanyard with that mysterious personage, at least by innuendo, had been unintentional. But somehow Lanyard didn't believe it had.
The two questions troubled him sorely: Did De Morbihan know, did he merely suspect, or had he only loosed an aimless shot which chance had sped to the right goal? Had the mind of Roddy proved fallow to that suggestion, or had it, with its simple national tenacity, been impatient of such side issues, or incredulous, and persisted in focusing its processes upon the personality and activities of Monsieur le Comte Remy de Morbihan? However, one would surely learn something illuminating before very long. The business of a sleuth is to sleuth, and sooner or later Roddy must surely make some move to indicate the quarter wherein his real interest lay.
Just at present, reasoning from noises audible through the bolted door that communicated with the adjoining bed-chamber, the business of a sleuth seemed to comprise going to bed. Lanyard, shaving and dressing, could distinctly hear a tuneless voice contentedly humming "Sally in our Alley," a rendition punctuated by one heavy thump and then another and then by a heartfelt sigh of relief—as Roddy kicked off his boots—and followed by the tapping of a pipe against grate-bars, the squeal of a window lowered for ventilation, the click of an electric-light, and the creaking of bed-springs.
