As it happens, Mr. Scaramucci wrote a book about his brief, unhappy White House experience, joining a large club of Trump administration evictees who have turned their bracingly bad experiences into a new genre of political revenge literature. These include James Comey, former F.B.I. director; Omarosa Manigault Newman, former assistant to the president; Andrew McCabe, former deputy F.B.I. director; John Bolton, former national security adviser; Cliff Sims, former White House communications aide; and Anonymous, current senior figure, at least by his or her own account, in the Trump administration.

(There’s also Sean Spicer, former press secretary, who wrote a mostly complimentary book about his fleeting White House tenure; and Mary Trump, not an ex-staffer but the president’s niece, whose scathing portrait of Trump family pathology came out in July and sold 1.35 million copies across all formats in its first week. That book is currently No. 1 on hardback nonfiction best-seller lists in the United States, Britain, Canada and Ireland, and No. 2 in Australia.)

Taken en masse, the books paint a damning portrait of the 45th president of the United States. But the sheer volume of unflattering material they contain can have the paradoxical danger of blunting their collective impact. After the 10th time you read about Mr. Trump’s short attention span, your own attention is in danger of wandering.
