6.1 pylon

It is the summer of 1969, and when a tough decade comes to an end, there is a change in Oxford. When we saw Endeavor Morse (Shaun Evans) for the last time, he and his colleagues suffered a terrible loss. The murder of George Fancy in a gangster gang shooting-an open and closed case-was not unleashed by the pathologist Max DeBryn (James Bradshaw), who revealed the deadly bullet, as something more complex was not fired by the gun that killed the men Fancy wanted to arrest at the time of his murder.

When we return to Morse eight months later, this mystery remains unresolved. The man who was once able to bring together the different threads of a case with the same efficiency he used in his beloved crossword puzzles is at a loss. Much has changed for Endeavor Morse, and the mustache he now wears is only the most obvious sign of his emotional turmoil. Still waters are deeper than ever before; Superficially everything is disturbingly quiet. After his few months with CID had come to a sudden end, he was forced to return to uniform. His rest is disturbed by a visitor. Jim Strange (Sean Rigby), who has still ridden up the ranks with a management post in the division, comes to his old friend's old one-man station to share whiskey and a clumsy chatter.

For one thing, it would have been weird who stifled nagging concerns and robbed past failures and injustices while Morse rejected the evidence. But now his efforts to get his former colleague to action fall on stony ground. Morse is tougher, cooler, more remote than we've ever seen him. He is polite and anything but unpleasant, but he has gone through too much to trust in investigation and fairness. After Thursday's catastrophic business with Fancy, Fred Thursday (Roger Allam) still had disciplinary hearings and demotions, but he just had enough. "Does not it interest you?" Asks Strange. "Would it make a difference?" Morse asks as he turns on his heel.

Morse has at least the privacy of his quiet little sanctuary to which he can retire. Thursday, however, is now responding to DCI Ronnie Box (Simon Harrison). If his name rings alarms, it should. Do you remember this glorious series five fight? Well, Box was the Sweeney-style copper – all alcohol, birds and Braggadocio – that cursed the much-missed honor of Shirley Trewlove and as a result experienced the wrath of the Lords of Cowley. Now he is in charge, and the misery on Thursday is over. Also between Fred and Morse is frost in the air, because their cozy lunchtime is a thing of the past.

When ten-year-old Ann Kirby disappears, personnel and police are used for the search. Only when Morse searches for a horse reported missing by Mr. Tingwell (Simon Hepworth) does the corpse of the child be found, placed in an eerie tableau in front of a power pole, as if it had been buried. DeBryn puts it on Thursday: "One would have known if anyone would find her, it would be him." The Interior Ministry scientist, as always, is full of pity on his dry joke. In brutal indignation over Box's tactless demands for sexual interference, DeBryn's natural understanding with the equally sensitive Morse on the same subject is a quiet pleasure: "And …?" "No, no." When these former colleagues elicit theories again, the Air crackles with her old energy. Box realizes it and he does not like it. One snap at a time jumps from Morse's tense frame as he bites hard on the tongue.

All evidence points to the drug-addicted Stanley Clemence (Aston McAuley), whose possession of her pouch by Box and his pointed colleague DS Alan Jago (Richard Riddell) is interpreted as a sign of guilt. Thursday does not share this view. In a stylish flashback – one of many pleasing visual decisions by director Johnny Kenton – we see Fred rescue the young man, then a toddler, from the house where his father brutally beat his mother. The tragedy will strike and corruption on a grand scale will be exposed before the innocence of the unfortunate youth is established too late.

The case itself is satisfactorily complicated, with a late stage involving Maggie and Alfred Skynner (Katharine Bubbear and Tom Canton) making an already devastating loss, the depth of which is skillfully conveyed by Fiona Skinner as the mother of a dead child scene of agonizing sorrow , The activities of the silly uncanny Dr. Lester Sheridan (Roger May) – completely incoherent with the death of poor Ann – apparently refer to the photography of author Charles Dodgson, who is known to posterity as Lewis Carroll, whose images of pre-pubescent girls he captures with his own annoying snapshots would like to copy. Sheridan's attempts to justify the abduction of Rosie Johnston (Abby Barnes) from a local festival, not to mention the three-year imprisonment of another missing child, sparked the anger on Thursday.

A spiky conversation between Endeavor and Joan (Sara Vickers), who now works as a social worker under the supervision of Viv Wall (Alison Newman), leads to conflicts for the future in an episode just before the jubilation. Nevertheless, we see that Chief Superintendent Bright (Anton Lesser, brilliant as ever) finds his calling in the transportation department with a training video that counts as one of endeavorThe biggest moments.

Oh, and when the episode ends, a bit of Morse story is made. While Barrington Pheloung's legendary theme spies on us, the young detective sergeant is on the way to the Thames Valley after Stranges request. When a decade comes to an end, a new era begins.
