Whats that got to do with him saying he received a call from Nevill?
A lot, considering that a DS stated he was ill-prepared for a huge investigation, meaning that he would and did bungle his way through in a slipshod manner. If someone was doing a job using the wrong tools then it would end in a mess wouldn't it ?
West would have, or rather DID speak to both men but got lost along the way because they happened to have been 2 Mr Bambers ! He obviously couldn't get his head around it because the calls came from different directions and not just the one address.
