Finally the connecting door gave, but with such a crash that I knew those outside must have heard. Instantly the outside knocking became a violent battering, while keys sounded ominously in the hall doors of the rooms on both sides of me. Rushing through the newly opened connexion, I succeeded in bolting the northerly hall door before the lock could be turned; but even as I did so I heard the hall door of the third room—the one from whose window I had hoped to reach the roof below—being tried with a pass-key.
     For an instant I felt absolute despair, since my trapping in a chamber with no window egress seemed complete. A wave of almost abnormal horror swept over me, and invested with a terrible but unexplainable singularity the flashlight-glimpsed dust prints made by the intruder who had lately tried my door from this room. Then, with a dazed automatism which persisted despite hopelessness, I made for the next connecting door and performed the blind motion of pushing at it in an effort to get through and—granting that fastenings might be as providentially intact as in this second room—bolt the hall door beyond before the lock could be turned from outside.
     Sheer fortunate chance gave me my reprieve—for the connecting door before me was not only unlocked but actually ajar. In a second I was through, and had my right knee and shoulder against a hall door which was visibly opening inward. My pressure took the opener off guard, for the thing shut as I pushed, so that I could slip the well-conditioned bolt as I had done with the other door. As I gained this respite I heard the battering at the two other doors abate, while a confused clatter came from the connecting door I had shielded with the bedstead. Evidently the bulk of my assailants had entered the southerly room and were massing in a lateral attack.
