Sorry, but I listened to the omnibus edition on Radio 4 extra and eventually had to turn it off. I found it trite, overblown, fantastical, not in accordance with my observation of peregrine behaviour, a fantasy, whimsy poor attempt at poetry, just a fondness for using many words when one would be enough.
Roping in D. Attenborough to narrate it in his usual soothing tones and condescension was the last straw.
Well past his sell by date and just blocking the career ladder for many talented people. No doubt when he pops his clogs there will be a great outpouring of sanctimonious faux grief for this national treasure. Whose talent appears simply to be a supreme narrator. Which is worthwhile. I understand that he knows a bit about fossils too.
