The terrifying rumors in an ancient library have caught the attention of three detectives. Upon entering the library, they were astonished to find a white-clad specter standing in the dimly lit stairwell, singing a desperate elegy. What surprised them was not her hideous appearance, but that she was known to two ordinary girls. What further aroused their suspicions was that when they attempted to investigate the case, they were sternly refused by the night watchman.

Was the boy who disappeared in the library years ago really killed by the gatekeeper? Is there a secret cabin on the top floor of the library? Does the white-clad specter really hide in the legendary, undiscovered basement? Through their investigation, the three detectives found that the truth was far from simple. The gatekeeper, who was always considered ordinary, turned out to be on friendly terms with books that could kill, and he even had a very prominent background...
