While visiting the theater, Thomas and Charlotte Pitt witnessed a tragedy - before their eyes, Judge Stafford of the Court of Appeal suddenly died. A flask was found with the deceased, in which whiskey was splashing... with a horse dose of opium tincture.

And if so, then the real killer may still be walking free...
