Mrs. Wilberforce is an eccentric old lady who lives in a house suffering from subsidence near King's Cross Station. She is offering rooms to let, an offer which is taken up by the sinister Professor Marcus.
Marcus claims that he wants to use the rooms so that he can practice with his string quintet, consisting of Major Courtney, Harry Robinson, 'One-Round' Lawson and Louis Harvey. In fact, they are armed robbers who use the the unwitting Mrs. Wilberforce to steal a large amount of money.
However, Mrs. Wilberforce discovers what is going on. After the robbers fail to convince her not to go to the police, they decide that the only way to get around the problem is to kill her, but does anyone have the guts?
