J. R. Ackerley, author of that remarkable book My Dog Tulip, worked for the BBC for many years and in that capacity oversaw the production of The Scoop (1931), a detective story written by six authors, each of whom read his or her contribution on-air. Dorothy L. Sayers coordinated the project; she was probably the only person who could have gotten the shy and retiring Agatha Christie to participate. But she and Ackerley continually butted heads, as he wished to provide editorial oversight that Sayers flatly rejected.

Some years later Ackerley wrote in a BBC memo

So far as I recall Agatha Christie, she was surprisingly good-looking and extremely tiresome. She was always late sending in her stuff, very difficult to pin down to any engagements and invariably late for them. I record these memories with pain, for she is my favourite detective story writer.

Her success as a broadcaster has made less impression upon me. I believe she was quite adequate but nothing more; a little on the feeble side, if I recollect aright, but then anyone in that series would have seemed feeble against the terrific vitality, bullying and bounce of that dreadful woman Dorothy L. Sayers. 

Whether Sayers was indeed “bullying,” or simply a woman who refused to be dictated to by men who were accustomed to dictating to women, is a matter of dispute. Later, when she was writing the plays that would become The Man Born to be King, she responded to an interfering producer thus: “Oh no you don’t, my poppet!” That producer was removed from the project — and replaced by one of the greatest theatrical producers of the twentieth century, Val Gielgud (brother of the actor John). However “difficult” she might have been, she couldn’t be dispensed with; in the end, it was almost always her critics who had to give way. 

But “vitality, bullying and bounce” is a great phrase, and many people found DLS similarly intimidating, and too energetic for comfort. But not everyone disliked the bounciness. On her death, C. S. Lewis wrote, “I liked her, originally, because she liked me; later, for the extraordinary zest and edge of her conversation — as I like a high wind.” And in a memoir Val Gielgud wrote, “Miss Sayers is professional of the professionals. She can tolerate anything but the shoddy or the slapdash. Of all the authors I have known she has the clearest, and the most justifiable, view of the proper respective spheres of author and producer, and of their respective limitations. She is authoritative, brisk, and positive.” 

Vitality, bounce, zest, edge, authoritative, brisk — a high wind indeed. No wonder responses to her were so mixed. She’s gonna be so much fun to write about.
