Definitely. I think it’s a really under-explored aspect of the case. Was Suzy targeted or would any female have sufficed? When Suzy leaves the office that lunchtime, is she going to 37SR fully believing she’s about to show a guy called Mr Kipper the house? When has Kipper made this appointment? And how? In person, or on the phone? Has he lucked out by getting through to Suzy, if she was indeed his target? Does he request to view 37SR specifically?
The truth is these questions can’t easily be answered even after all this time.
If Mr Kipper was a guy posing as a house buyer in order to abduct/rape/murder a female estate agent then sure, it could’ve been Cannan. But nothing especially points to him. He’s just a sex offender who’d been in the area in an era when attacks on female estate agents and homeowners in the process of selling their houses were depressingly common.
No paper trail and obviously no digital one, no crime scene, and no body, all make this a devilishly tough case to crack. But for the Met to kid on like they have indeed cracked it, when they really know next to nothing, is wild.
