The Simon Guerrier (writer's name) trilogy begins with The Perpetual Bond, and Story kicks of something brilliant, The Perpetual Bond is the beginning of a brilliant trilogy. The story introduces Oliver Harper, the latest companion, from the 1960's (probably 1966), who has a (in his opinion) a terrible secrete (did I just give a clue of what the secrete is?), which we won't learn in this story, but in the next story of the trilogy The Cold Equations. (Don't get too disappointed; it's not that great anyway). The atmosphere feels like the 1960's as well.
Tom Allen playing Oliver Harper is brilliant, he sound just like a young 1960's dealer, as well as Peter Purves as Steven Taylor, who sounds just like he did when he was doing Doctor Who in 1965/1966. They both produce top rated voices; they also make it feel like there are 4 people doing this audio story (there are only 4 main characters in this, The first Doctor, Steven, Oliver and Mr Flowers, the alien) when in fact it is just them two. Peter Purves's first Doctor voice, may not sound exactly like Bill `s, but I was shocked that he was doing the doctors voice when I heard it when the cast were talking about the story at the end. That's how good he is, and Tom Allen's Mr Flowers voice was quite good too (he was using a machine to disguise it up.) So it sound like a 4 people cast drama.
The story is great; the cast is great, and it's only on for an hour (part 1 and 2 both last for 30 minutes (part 2 is better then the 1'st) which makes an hour), to sum up, it is well worth having, A good starter for a good trilogy. Get this now!!!, get it, GET IT!!!! GET IT!!!!!!!!!!!!!!!!
