A University of Toronto professor's 10-year-old book is back on the bestseller list thanks to rampant public interest in Capitol Hill tell-all Fire and Fury: Inside the Trump White House.

Randall Hansen, interim director at the Munk School of Global Affairs, wrote his own Fire and Fury to chronicle an Allied bombing campaign on German civilians during the Second World War.

The similarity in titles between Hansen's book and Michael Wolff's instant bestseller about U.S. President Donald Trump means both get called up in an online search.

While Hansen dug into 1940s military history in his 2008 read, Wolff's book portrays Trump as a leader who doesn't understand the weight of his office and whose competence is questioned by aides.

The latter has seen "unprecedented demand" running up to its release on Friday, according to the publisher, and has since latched onto the top spot on Amazon's bestseller list.

The similarity apparently also confused or enticed more than a few buyers into ordering Hansen's book, landing it in the top 100 in three of Amazon's sales categories.

'I had a chuckle'

Attending a conference in Washington, D.C., itself when Wolff's book was released, Hansen joked with colleagues about the titular similarities.

"I was hearing Fire and Fury left and centre and perking up a little bit," he said, but aside from gentle amusement thought little of the coincidence.

Later on Friday night, he searched for the title on a whim, surprised to see his 2008 book featured on Amazon alongside Wolff's new release.

"I saw that my book, which came out 10 years ago and had been languishing for quite a while in terms of sales numbers, was suddenly in three Amazon bestseller lists," he said. "I had a chuckle to myself."

'Ironic' coincidence

Hansen tweeted casually about his work's resurgence on Friday when he noticed sales were up, but woke up on Saturday to another surprise — the tweet went viral.

Hansen, who describes himself as a "devout critic" of Trump and the president's former chief strategist, Steve Bannon, can't put his finger on why, but he hinted at another possible cause of his boosted sales.

Incredibly, sales of my <a href="https://t.co/8VeAA9DCFT">https://t.co/8VeAA9DCFT</a> have increased. Will I owe a larger royalty cheque to Bannon & Trump? If so, the irony will know no limits. <a href="https://twitter.com/hashtag/FireAndFury?src=hash&ref_src=twsrc%5Etfw">#FireAndFury</a> —@ProfRAHansen

Some may have found it amusing, he guessed, "that someone like me was benefiting from something, published with Bannon's help, about Trump."

More seriously, Hansen said, the book's renewed popularity might highlight the time-worn risks of relying on military force, even though the two tomes have little else in common.

Hansen argued that the bombing campaign against Hitler's Germany that killed half a million civilians was "needless," and hopes Fire and Fury: The Allied Bombing of Germany, 1942-1945 can highlight the immutable consequences of war for the book's newest readers.

"If at this moment we have this unstable demagogue as president — who loves threatening war, and saying, 'My nukes are bigger than your nukes," and all this rubbish — if at this moment people reflect through my book on the utter horror of war, what it does to human bodies, its appalling consequences above all for civilians, then that'll be both politically important but also gratifying."
