That the search for the missing phial was likely to be a long-continued one soon became apparent to everyone. Two men who had carried the investigation into the room where the servants had been shut up since early evening, came back with the report that nothing had come to light in that quarter. At the same time two more returned from above with a similar report in regard to the sleeping-rooms of the three brothers. Sweetwater and Gryce, who had spent the last half-hour in the dining-room, appeared to have an equally unsatisfactory tale to tell, and I was wondering what move would now be made, when I intercepted a glance from the coroner cast in the direction of the drawing-room, and realised that the law was no respecter of persons and that she, she too, might be called upon to give proof of not having this tell-tale article upon her person.

The prospect of such an indignity offered to one I regarded with more than passing admiration unnerved me to such an extent that I was hardly myself when Dr. Frisbie advanced upon me with this remark:

"I regret the necessity, Mr. Outhwaite; but the emergencies of the case demand the same compliance on your part as on that of the other gentlemen found upon this scene of crime. It is needless to say that we have the utmost confidence in your integrity, but you were here when Mr. Gillespie died, and have been close to a certain member of this family many times since—and, in short, it is a form which you as a lawyer will recognise and——"

"No apologies," I prayed, recalling the one son of Mr. Gillespie who had not been on the scene of crime at the time of his father's death.

An intelligent glance from the coroner convinced me that he was thinking of him too. Indeed, he seemed to be more than willing to have me understand that he exacted this thorough search in order to fix the crime on Leighton. For if the phial was not to be found anywhere in the house, the necessary conclusion must be that it had been carried out of it by the one person known to have left it during the critical half-hour preceding Mr. Gillespie's death.

"I understand your thoughts," quoth the coroner, who seemed to read my face like an open book. "The phial may have been smashed on the sidewalk or thrown into some refuse barrel. But that would be the unwisest thing a guilty man could do. For its odour is unmistakable, and once it is found by the men I will set looking for it at daybreak—Well, what now?"

Sweetwater was whispering in his ear.

"The child? Do I remember that the father suggested she should be put to bed undressed? Oh, I cannot have you disturb the child. Used as I am to the subterfuges of criminals I find it impossible to believe that a father could make use of his child as a medium for his own safety."

"Or Miss Meredith?" the insidious whisperer went on.

"Or Miss Meredith. She may have the bottle on her own person, but she would never pass it over to the child. No, no! curb your extravagances and confine your attention to Mr. Outhwaite, who is kind enough to allow us to inspect his pockets——"
