A very good story,including in a quite faithful way,some of the Labours Of Hercules,in a claustrophobic mix,full of anguish,sadness and thrills.THe prologue is quite Scream-like without the gore.The death of Lucinda is perhaps the most thrilling in the entire series,a good set-up for a slasher without the on-screen slashing.THe hotel in Switzerland, with cable-car annexed,is wonderfully rendered...in England,and it gives a sense of Mousetrap and Orient express combined.THe stories quite faithfully developed are Birds,Cerberus ,Deer and ,of course,Boar,the principal source of this story who can be considered half a pastiche of Christie and half a faithful adaptation of some of her tales.Very curiously,it's more faithful than Appointment ,and the solution is basically the same of the tales with no change of culprits,but instead a blending of different culprits from different tales.The love story of the chauffeur is beautifully rendered,and the final solution is pleasant,not so chaotic,and it can give to us a glimpse of what it could have been Bertram (hidden paintings included) if it could have been made well.Among the best actors,apart from colossal,herculean Hercule,an excellent Eleanor Tomlinson,MCDade and Christie as two well understated Stymphalean Birds and Rupert Evans as a dashing hero. It's a pity that many of the other Labours and Lemesurier inheritance were not been adapted as promised,and I will wait forever for a new series with Suchet even if it's hopeless.But as an ending of a monumental series,season 13 has been really a masterpiece ,one of the best of the whole series!!!!
