That Night at the Museum

After closing, the special-exhibition hall should hold nothing but the hum of the air-conditioning and the footsteps of the intern on night duty. On the night of October 14, there was something else in it.

The museum's handling procedure is explicit: after closing, the special exhibits are left to a single student on duty for the terminal inventory check and the surveillance handover, with the night-shift guard taking over at 22:30. The 21:12 inventory record that night was normal throughout, the sign-off column filled in, no remarks.

21:34. The air-conditioning hummed once and dropped 0.7 degrees. The environmental conditions for this exhibit are written into the loan agreement, 21°C ±0.3 and 50% RH ±5, but the environmental monitoring panel in the corner held steady at 21°C, the number never so much as flickering. The gooseflesh on the skin was one layer thicker than it had been on the way in.

21:36. On the inner side of the glass display case, on the face nearest the head of the sarcophagus, a layer of mist came up. The case is double-glazed, the interspace nitrogen-filled, the outer layer independently dehumidified; mist should not appear on the inside, and it should not fail to slide down. The wrist terminal could not catch it. Switched to RAW, another frame, magnified 200%: the image was still clean.

21:41. From the bottom of the sarcophagus came the sound of a fingernail tapping, the rhythm irregular, growing clearer from the fifth tap on. 21:44. The surveillance feed ran 3 seconds late—a person took two steps to the left, and the person in the picture took them 3 seconds afterwards. 21:47. The LED exhibition guide lightbox on the wall began rewriting itself from the first character on, the Chinese turning into hieroglyphic components rotated 30 degrees.

21:48:03. Every exit in the hall vanished at the same moment. The doors were still there, the frames were still there, and behind the frames was freshly laid brick with the mortar still wet. The emergency phone, lifted off its cradle, gave no dial tone, only a distant noise on the line, something like breathing.

22:04. Everything went back to what it had been: the mist gone, the lightbox snapped back to the Chinese title, the signal restored. After that night, the person on night duty never fit back inside the words "museum intern" again.

The next day the "Past 24 Hours" record was pulled off the environmental monitoring: at that second at 21:34 there was no 0.7-degree drop. The surveillance footage was pulled: the student on duty patrolled normally, worked through the steps, finished signing, walked out of the hall, and in those 90 minutes from 21:00 to 22:30 there was not one abnormal second. In every system the museum has, that night never happened.
