The Great Detective

When Sir Arthur Cwmlech's home is robbed and the Illogic Engine - his prize invention-stolen, it is only natural that he and his clever assistant Miss Tacy Gof consult with another inventor, the great Mycroft Holmes, about who has taken it. But it is really Mr. Holmes' Reasoning Machine who they are there to see, for it is only fitting for one automaton to opine on a matter concerning the fate of another of its kind.
