So instead, I was extremely polite, regretted to have troubled him, and, raising my hat, withdrew.

I saw that to remain within the big office for hours was impossible. The uniformed doorkeeper who sat upon a high desk overlooking everything, would quickly demand my business, and expel me.

No, my only place was out in the open street. Not a pleasant prospect in winter, and for how many days I could not tell.

For aught I knew, the fugitive had called for the woman's letter and left the capital. But he, being aware that the police were in search of him, would, I thought, if he called at the post office at all for letters, come there after dark. Hence, I had lost no time in mounting guard.

My thoughts, as I stood there, were, indeed, bitter and confused.

The woman Petre had not, as far as I could make out, made any incriminating statement to the police. Yet she undoubtedly believed me to be dead, and I reflected in triumph upon the unpleasant surprise in store for her when we met—as meet we undoubtedly would.

The amazing problem, viewed briefly, stood thus: The girl, Marie Bracq, had been killed by a knife with a three-cornered blade, such knife having been and being still in the possession of Phrida, my well-beloved, whose finger-prints were found in the room near the body of the poor girl. The grave and terrible suspicion resting upon Phrida was increased and even corroborated by her firm resolve to preserve secrecy, her admissions, and her avowed determination to take her own life rather than face accusation.

On the other hand, there was the mystery of the identity of Marie Bracq, the mystery of the identity of the man who had passed as Sir Digby Kemsley, the reason of his flight, if Phrida were guilty, and the mystery of the woman Petre, and her accomplices.

Yes. The whole affair was one great and complete problem, the extent of which even Edwards, expert as he was, had, as yet, failed to discover. The more I tried to solve it the more hopelessly complicated did it become.

I could see no light through the veil of mystery and suspicion in which my well-beloved had become enveloped.
