Madame Bonacieux’s bosom heaves in an impressive fashion as D’Artagnan attempts to divine the reason why she was targeted by the Cardinal’s men. A very blatant boom shadow is a little bit of a distraction, but there’s another example of Peter Hammond’s quest to find interesting camera angles – the conclusion of the scene is shot directly at a mirror, showing us the reflections of Madame Bonacieux and D’Artagnan.

Monseuir Bonacieux finds himself a prisoner in the Concierge, questioned by the relentless Commissary (Vernon Dobtcheff). Making his sole appearance in the serial, Dobtcheff’s another very dependable actor who’s always a joy to watch – his relentless bullying of Paul Whitson- Jones’ hapless Bonacieux is very nicely played. The Commissary is further irritated when he’s presented with someone whom he believes to be D’Artagnan, but turns out to be Athos. This shows us Athos’ chivalrous side – he doesn’t deny that he’s not D’Artagnan in order to enable his friend to remain at liberty – but Jeremy Young still remains the least developed of the Musketeers at this point.

Jeremy Brett continues to chew the scenery as his love for Madame Bonacieux deepens, as does his paranoia that she loves another (and he seems to have forgotten that she’s a married woman anyway!) “Madame, if you could see my heart, you would discover so much love.” At present she can’t reciprocate, telling him that she has gratitude for him, but little else. The arrival of a strange man provides more fuel for D’Artagnan’s jealousy. But the Duke of Buckingham (Simon Oates) hasn’t got his eyes on Madame Bonacieux, he’s aiming a little higher …..

Oates, later to star as the womanising, foppish scientist John Ridge in Doomwatch, plays a womanising foppish member of the English nobility here. So not too much of a stretch. He does seem to be enjoying himself though, as he clearly relishes the ripe dialogue. More restrained performances can be seen when the disheveled Monseuir Bonacieux is brought into the presence of the Cardinal. If Buckingham and the Queen are florid and histronic then the Cardinal and Rochefort continue to downplay. This is an interesting choice, as you’d normally expect the villains to offer broad and moustache twirling performances.

Brian Blessed and Gary Watson only pop up towards the end of the episode. Blessed remains as loud as you might expect, but he’s also as entertaining as you might expect too. He tells D’Artagnan and Aramis that he has an assignation with a noble lady and takes his leave of them.  But the truth is somewhat different – he finds his pleasures with women from a lower class of society (pride prevents him from admitting the truth). It’s a nice character beat and the brief following scene is played well by Blessed, as Porthos momentarily show irritation when he’s in the company of his latest date, before he puts on a brave face and makes the best of it.

More bosoms heave as Milady de Winter reappears. The Cardinal has learnt that the Queen gave Buckingham a casket containing twelve diamond studs gifted to her by the King. It seems rather strange that not only would she decide to give away a present presented to her by her husband but also one that would be so identifiable. The Cardinal sends Milady de Winter to England with the clear directive to obtain several of these studs. Once a link between the Queen and Buckingham can be proved, the Cardinal will have all the evidence he needs to bring the monarchy crashing down …..
