Refreshed by a good night’s rest and quite ready to take up his task again, Mr. Gryce sat at the same table in the early morning, awaiting the expected message from Sweetwater. Meanwhile he studied, with a fuller attention than he had been able to give it the evening before, the memorandum which this young fellow had handed him of his day’s work. A portion of this may be interesting to the reader. Against the list of people registered on his chart as present in the museum at the moment of tragedy, he had inscribed such details concerning them as he could gather in the short time allotted him.

I— Ephraim Short. A sturdy New Englander visiting New York for the first time. Has a big story to take back. Don’t care much for broken marbles and pictures so dingy you cannot tell what you are looking at; but the sight of a lot of folks standing up like scarecrows in a field, here and there all over a great building, because something had happened to somebody, will make a story the children will listen to for years.

Address taken, and account of himself verified by telegraph.

II— Mrs. Lynch. Widow, with a small house in Jersey and money to support it. No children. Interested in church work. Honest and of reliable character. Only fault a physical one — extreme nervousness.

III— Mr. Carleton Roberts, director; active in his work, member of the union League and an aspirant for the high office of U. S. Senator. Lives in bachelor apartment, 67 W. —— Street. A universally respected man of unquestioned integrity and decided importance. Close friend of Curator Jewett.

IV— Eben Clarke, door-man. Been long in the employ of museum. Considered entirely trustworthy. Home in decent quarter of West 80th Street. Wife and nine children, mostly grown. Never been abroad. Has no foreign correspondence.

V— Emma Sutton, an art enthusiast, gaining her living by copying old masters. Is at museum six days in the week. It was behind her easel Travis found a hiding-place in Room H.

VI— Mrs. Alice Lee, widowed sister of Edward Cronk Tailor, —— Sixth Ave. Lives with brother. Kindly in disposition, much liked and truthful to a fault. No acquaintance abroad.

VII-VIII— John and Mary Draper, husband and wife, living in East Orange, N. J. Decent, respectable folk with no foreign connections.

IX— Hetty Armstrong, young girl, none too bright but honest to the core. Impossible to connect her with this affair.

X— Charles Simpson, resident of Minneapolis. In town on business, stopping at Hotel St. Denis. Eager to return home, but willing to remain if requested to do so. Hates foreigners; thinks the United States the greatest country on earth.

XI— John Turnbull, college professor; one of the new type, alert, observant and extremely precise. Not apt to make a misstatement.

XII— James Hunter, door-man, a little old for his work, but straight as a string and methodical to a fault. No wife, no child. Bank account more than sufficient for his small wants.

XIII— Miss Charlotte Hunsicker, one of last season’s débutantes. Given to tennis and all outdoor sports generally. Offhand but stanch. It was she who gave a woman’s care to Mrs. Taylor when the latter fainted in Room B.

XIV— Museum attendant coming up from basement.

XV— Eliza Blake a school-teacher, convalescing after a long illness.

XVI— Officer Rudd.

XVII— Tommy Evans, boy scout. Did not lose his game. Went to the field after lunching on pie at a bakery.

XVIII— Mrs. Nathaniel Lord, wealthy widow, living at the St. Regis.

XIX— Mrs. Ermentrude Taylor. (Nothing to add to what is already known.)

XX— Henry Abbott, Columbia student, good-hearted and reliable, but living in a world of his own to such an extent as to make him the butt of his fellow students.

XXI-XXII— Young couple from Haverstraw. Just married. He a drug-clerk, she a farmer’s daughter. Both regarded in their home town as harmless.

XXIII— James Correy, attendant. Bachelor, living with widowed mother. Fair record on the whole. Reprimanded once, not for negligence, but for some foolish act unbecoming his position. Thorough acquaintance with the museum and its exhibits. A valuable man, well liked, notwithstanding the one lapse alluded to. At home and among his friends regarded as the best fellow going. A little free, perhaps, when unduly excited, but not given to drink and very fond of games. A member once of a club devoted to contests with foils and target-shooting. Always champion. Visits a certain young lady three times a week.

XXIV— Curator Jewett. A widower with two grandchildren — a daughter married to an Englishman and living in Ringold, Hants, and a son, owner of a large ranch in California. Lives, when in city, at Hotel Gorham. Known too well for any description of himself or character to be necessary here. If he has a fault, or rather a weakness, it is his extreme pride in the museum and his own conduct of its many affairs.

As on the evening before, Mr. Gryce lingered longest over one name. He was still brooding anxiously over it when the telephone rang at his elbow and he was called up from Headquarters. Cablegrams had been received from London and Paris in acknowledgment of those sent, and in both these cablegrams promises were made of a full examination into the antecedents of Madame Duclos and her companion, Miss Willetts.

That was all. No further news regarding them from any quarter. Mr. Gryce hung up the receiver with a sigh.

“It is likely to be a long road full of unexpected turns and perilously near the precipice’s edge,” he muttered in weary comment to himself. “Nothing to start from but ——”

Here Sweetwater walked in.

Mr. Gryce showed surprise. He had not expected to see the young man himself. Perhaps he was not quite ready to, for he seemed to shrink, for one brief instant, as from an unwelcome presence.

But the cheer which always entered with Sweetwater was contagious, and the old detective smiled as the newcomer approached, saying significantly:

“I had those dreams you spoke of last night, Mr. Gryce, and found them too weighty for the telephone.”

“I see, I see! Sit down, Sweetwater, and tell me how they ran. I haven’t as much confidence in my own dreams as I hope to have in yours. Speak up! Mention names, if you want to. No echo follows confidences uttered in this room.”

“I know that; but for the present perhaps it will be best for me to follow your lead, and when I have to speak of a certain person, say X as you do. X, Mr. Gryce, is the man who for reasons we do not yet understand brought up the discarded bow from the cellar and stored it somewhere within reach on the floor above. X is also the man who for the same unknown reason robbed the quiver hanging in the southern gallery of one of its arrows and kept the same on hand or in hiding, till he could mate it with the bow. My dreams showed me this picture:

“A man with a predominating interest in sport, but otherwise active in business, correct in his dealings and respectable in private life, sees and frequently handles weapons of ancient and modern make which rouse his interest and awaken the longing, common to such men, to test his skill in their use. Sometimes it is a sword, which he twirls vigorously in sly corners. Again, it is a bow calling for a yeoman’s strength to pull. He is a man of sense and for a long time goes no further than the play I have just indicated. Perhaps he has no temptation to go further until one unfortunate day he comes upon an idle bow, rotting away in the cellar.”

Here Mr. Gryce looked sharply up — a proof of awakened interest which Sweetwater did not heed. Possibly he was not expected to. At all events he continued rapidly:............
