"As twilight deepened I turned on the one feeble electric bulb over the cheap, iron-framed bed, and tried as best I could to continue the reading I had begun. I felt it advisable to keep my mind wholesomely occupied, for it would not do to brood over the abnormalities of this ancient, blight-shadowed town while I was still within its borders."
"It would perhaps have been easier to keep my thoughts from disturbing topics had the room not been so gruesomely musty. As it was, the lethal mustiness blended hideously with the town's general fishy odour and persistently focussed one's fancy on death and decay."
"Another thing that disturbed me was the absence of a bolt on the door of my room. One had been there, as marks clearly shewed, but there were signs of recent removal. No doubt it had been out of order, like so many other things in this decrepit edifice. In my nervousness I looked around and discovered a bolt on the clothes press which seemed to be of the same size, judging from the marks, as the one formerly on the door. To gain a partial relief from the general tension I busied myself by transferring this hardware to the vacant place with the aid of a handy three-in-one device including a screwdriver which I kept on my key-ring. The bolt fitted perfectly, and I was somewhat relieved when I knew that I could shoot it firmly upon retiring. Not that I had any real apprehension of its need, but that any symbol of security was welcome in an environment of this kind. There were adequate bolts on the two lateral doors to connecting rooms, and these I proceeded to fasten."
"Then, after a long, dreary interval, and prefaced by a fresh creaking of stairs and corridor, there came that soft, damnably unmistakable sound which seemed like a malign fulfillment of all my apprehensions. Without the least shadow of a doubt, the lock of my door was being tried--cautiously, furtively, tentatively--with a key."
"After a time the cautious rattling ceased, and I heard the room to the north entered with a pass-key. Then the lock of the connecting door to my room was softly tried. The bolt held, of course, and I heard the floor creak as the prowler left the room. After a moment there came another soft rattling, and I knew that the room to the south of me was being entered. Again a furtive trying of a bolted connecting door, and again a receding creaking."
"I knew that the time for action had come, and forthwith drew the bolt of the northward connecting door, bracing myself for the task of battering it open. The knocking waxed louder, and I hoped that its volume would cover the sound of my efforts. At last beginning my attempt, I lunged again and again at the thin paneling with my left shoulder, heedless of shock or pain. The door resisted even more than I expected, but I did not give in. And all the while the clamour at the outer door increased." -- The Shadow Over Innsmouth
