“This clever, yeasty detective yarn is like a runaway hansom cab that pauses just long enough to take on passengers ranging from Darwin to Dickens before hurtling onward. It’s a grand ride, a serious education and a delightful addiction.” 

– Louis Bayard, author of Courting Mr. Lincoln

“I am a big fan of Charles Dickens, and the Dickens influence permeates the whole book. In addition to the era in which it is set, the plot is twisty in ways that I think Dickens would admire, and there is a cadre of ragtag children and quirky characters who would be right at home in a Dickens novel… The Darwin Affair is a thrilling suspense tale that will tempt you to race through for the story alone, but slow down long enough to enjoy the writer’s craft.”

– Angie Boyter

“The Darwin Affair is a page-turner that moves at high speed from beginning to end… looks made to order for a Hollywood film and Tim Mason appears to be just the right person to write the screenplay… I am sure that we have not seen the end of Detective Field and I look forward to his return.”

– Russell Fanelli

“…a fast-paced historical mystery…”

“With many grisly murders and many shocking surprises along the way, the book rockets toward a last dark twist. Careful research, a driving plot, wry wit, and compelling characters make this a most entertaining read.”

– Kirkus Reviews
