I was drawn to review the cadaver dog examination & alert in 5A following a recent discussion elsewhere.
On watching the sequence of events starting at 19m 16s on the attached link (full screen on a laptop/desktop is recommended)
https://youtu.be/c4NMYPsFKb8?t=1156 right through to the time of Eddie's alert, it is very interesting to note where Eddie's nose can briefly be seen before he turns around behind the sofa & starts barking. His tail is visible, showing his position when alerting.
I have included a still shot where you can see his nose just before the alert.
Contrast this with the commentary Grime provided on the location of the source of the alert at the time:-

"Moving onto the other rooms once he's found what he thinks he's looking for in this room, and we go into the bathroom and come into this bedroom he loses his interest because he's actually found the source that he was looking for, until we come over here and I think you've got it on video that when he first came in he was quite interested in the sofa but he didn't have access to the back of the sofa and when he's gone behind the sofa what I saw was that
approximately in the centre of the wall where the window is, just along the tile area between the tiles and the wall, he's been scenting there a lot stronger than he has anywhere else and the when he's gone out there the second time he has decided yes that's what I'm looking for and that's when he has given me the bark indication."What observations do other posters have regarding what appears to be the real source of Eddie's alert?
