Usually they looked past me hopefully and some even went and peered into the car to see if the man they really wanted was hiding in there. And it was uphill work examining an animal when its owner was chafing in the background, wishing with all his heart that I was somebody else. But I had to admit they were fair. I got no effusive welcomes and when I started to tell them what I thought about the case they listened with open scepticism, but I found that if I got my jacket off and really worked at the job they began to thaw a little.
