dealings

I trust that I am not more dense than my neighbours, but I was always oppressed with a sense of my own stupidity in my dealings with Sherlock Holmes.

None of the Sloanes would have any dealings with the Bells, because the Bells had declared that the Sloanes had too much to do in the program, and the Sloanes had retorted that the Bells were not capable of doing the little they had to do properly.
