Sherlock Holmes wakes up Dr. Watson early one winter morning to rush to a murder scene at the Abbey Grange near Chislehurst, Kent. Sir Eustace Brackenstall has been killed, apparently by burglars. Inspector Stanley Hopkins believes that it was the infamous Randall gang who have committed several other burglaries in the neighbourhood. At Abbey Grange, Lady Brackenstall tells Holmes that her marriage was not happy; Sir Eustace was a violent, abusive drunkard. She then tells that about 11 o'clock, in the dining room, she encountered an elderly man coming in the French window, followed by two younger men. The older man struck her in the face, knocking her out. When she came to, she was gagged and tied to an oaken chair with the bellrope, which they had torn down. Sir Eustace came into the room and rushed at the intruders, one of whom struck and killed him with a poker. Lady Brackenstall fainted again for a minute or two. She saw the intruders drinking wine from a bottle taken from the sideboard. Then they left, taking some silver plate.

Sir Eustace's corpse is still lying at the murder scene. Examining the bellrope, Holmes notes that if it was tugged hard enough to tear it down, the bell would have rung in the kitchen, and asks why nobody heard it. Hopkins answers that it was late, and the kitchen is at the back of the house, where none of the servants would have heard. This suggests that the burglars must have known this, indicating a link between them and one of the servants. Oddly, the thieves stole only a few items of silver plate from the dining room. The half-empty wine bottle and glasses interest Holmes – the cork had been drawn with the corkscrew of a "multiplex knife", not the long corkscrew in the drawer, and one of the glasses has beeswing dregs in it, but the others have none.
