Slightly torn but invested for what's next
Format: Paperback
This is my first Benedict Brown book. I don't know what it was that it was difficult for me to "get into" this book. It almost felt dragged out in some parts instead of getting to the point. And other times it felt like the author was trying too hard, if that makes sense. Each time I picked it up, it took a bit to warm up to it then I couldn't put it down. Then again, I'd stop and have to start that process all over again and I have no idea why. It is funny in parts. Definitely a cozy mystery, none of the blood and gore.
I did enjoy the twist, although it was in the back of my mind from the onset. I wouldn't say I won't read the next one, sometimes the first book in a series is not always the best....oddly I've found myself endeared to Marius and feel invested in knowing what adventure he'll face next!

Great new 1920's British Mystery Series
Format: Kindle
This is a 1920’s British mystery along the lines of Agatha Christie’s classic novels. It is the first book in the series and features a mystery writer – Marius Quin. The book begins with Quin having successfully published his first novel, but having problems meeting his publisher’s demand for a second. Depressed when he leaves his publisher’s office, he accidentally meets an old love of his, Bella, a woman he had wanted to marry ten years before but, because he was leaving to fight in WWI, he didn’t propose. It is Bella who invites him to a New Year’s Eve weekend party at Everham Hall, home of a famous film actor. During the weekend, one of their party is killed and so begins the hunt for the murderer, with Marius and Bella investigating. There are plot twists and turns until the denouement when the killer is revealed. I really like both of the main characters (Marius Quin and Bella), and I’m a fan of that time period and of country manor mysteries. I’ve enjoyed Benedict Brown's Lord Edgington novels and find this new series equally appealing.

New Year, new beginnings, new murder
Format: Kindle
Having run through the entire Lord Edgington Investigates series, it felt natural to jump over to this Marius Quin mystery. All in all, it’s not quite as funny as the banter between Lord Edgington and Christopher affords, but it’s still highly readable and offers the same weaving of clues to keep you entertained.
What’s in store for you? Put together looming bills, writer’s block, a past lover, a New Year’s Eve party, a dead silent film star, a killer on the loose in a snowbound manor, and 6 perfectly good suspects—except they all seem so innocent if unlikeable (some more than others, one more than most)—which means Marius has his work cut out for him. So do you if you’re an armchair detective.
So why 3 stars and not higher? I’m suffering from comparison syndrome. Marius and Bella don’t have a big enough gap between them (other than an historical romantic mishap) for belly-laugh comedic moments like Lord Edgington and grandson Christopher have. That won’t stop me from reading the next installment in the series, though, so I can let Marius and Bella grow on me as the author finds their rhythm.

Grown up version of Chrissy!
Format: Kindle
Marius Quin is a good character for Benedict Brown’s readers. There is a tie-in with Lord Edgington (and Chrissy) and Lord Edgington is referred to or almost mentioned a few times. This takes place in a huge old mansion with some history, that has to do with the murder, so I don’t want to spoil it. Marius does have a dog, but he’s not as involved with the story as Lord Edgington’s Golden Retriever, unless you think of his ability to judge characters.

A quite enjoyable, funny, mystery.
Format: Kindle
I really enjoyed this one, it was funny, great characters, fantastic pacing, solid twist at the end, although one thing was obvious to me but I can't say it because thats a spoiler. But I am really looking forward to the next book.
