This original Sherlock Holmes case (from a story by Anthony Hinds under his John Elder alias) also marks Peter Cushing's last starring role – he had first played the fastidious Baker Street detective in Hammer's 1959 version of THE HOUND OF THE BASKERVILLES, reprised in two TV series in 1964 and 1968 (during the course of which he eventually relinquished the part to Douglas Wilmer). His inseparable sidekick, Dr. John Watson, was interpreted by the likes of Andre' Morell, Nigel Stock and, here, Sir John Mills. Incidentally, given the actors' age, the film starts off with Holmes (typically and, in spite of Cushing's frail look, he is made to don a couple of disguises throughout) in retirement, his adventures being recounted to reporter Susan Penhaligon – whose appearance is relegated to this brief prologue, never subsequently picked up! Seeing the cast at work, one gets the feeling he is visiting a veterans' retirement home: supporting the leads, among others, are Ray Milland and Anne Baxter (both of whom would be dead within 2 years), Anton Diffring and Gordon Jackson! Anyway, the main narrative – set on the eve of WWI – seems to incorporate two unrelated mysteries (mildly thrilling but not really horrific, as I had been led to believe!) but which, unsurprisingly, are found to be connected: the first involves a number of corpses discovered bearing the titular countenance, the second the alleged kidnapping of the young heir to the German throne. The main setting, then, is Diffring's county manor – where Holmes runs into an old nemesis, Baxter, one of the very few who had ever managed to outwit him! – but the climax takes place in an underground lair, with our heroes incongruously resorting to shooting their way out of trouble! All in all, the film is an adequate (and pleasingly old-fashioned) time-passer, its biggest reward undoubtedly emerging Cushing's always delightful turn as Sir Arthur Conan Doyle's master sleuth. Even so, the sheer fact that so many of its participants – Cushing, Diffring, Milland, Penhaligon, Ward Baker and Elder – had previously excelled in the horror genre makes the surprising lack of it here seem doubly disappointing.
