After a string of thefts from the Grange, George Biddle comes to call, in connection with Mrs Peacock's insurance claim. Who is the thief? And, indeed, was anything really stolen?

Biddle, an old friend of Colonel Mustard's, had promised him a directorship but had not delivered.

And did Mrs White really set fire to the last house she worked in?The real mystery is surely that Biddle managed to survive for more than five minutes at Arlington Grange.
