Blood Pressure (Serial Investigations Book 7) Kindle Edition

4.2 out of 5 stars 15 ratings

A victim locked in a closet.
A detective trying to get out.

Ram has spotted his dream locked room mystery case on the news – and he’ll stop at nothing to get himself involved with it. The problem is, newly-minted DCI Alex Heath isn’t too happy about it – and neither is his successor as DI…

An invitation to go home and visit family should be a happy occasion, but for Will, it’s quite the opposite. Spiralling into doubt and fear about Ram outing him to his parents, Will risks pushing his boyfriend away entirely. And when he does go home, things aren’t going to be plain sailing. Will’s father is an ex-Ambassador, and he’s got many years of finding out secrets behind him.

As both are rocked by revelations about Will’s past and his present, Ram and Will have to contend with doubting policemen, ugly habits rearing their heads, and the struggle to trust one another. And there’s the question of how Harry got that black eye…

If you’re a fan of hot gay romance, high-stakes drama mystery thrillers, or sharply witty Londoners, you’ll love Serial Investigations. Try to keep your cool in Blood Pressure, a mystery with lashings of anxiety and an ending that might just blow a family apart.

Click ‘buy now’ enter the minds of troubled yet brilliant detectives as they fight to get out of closets – both metaphorical and physical – with the ever-present threat of murder hanging over them.

Editorial Reviews

Review

"If you haven't read this series, you need to go back to book 1 and get started. It really is a series that is one to keep you hooked and on your toes. There's so much going on that each page is like another treasure to be found" - LoveBytes Reviews
"I couldn't wait to read book 7 in the series. I have loved Will and Ram since book 1 and the series just keeps getting better and better... The mystery is just as intriguing as ever and I enjoyed following the case and trying to work it out for myself too! Again it was full of suspense and twists that I never saw coming! I thoroughly enjoyed Blood Pressure" - Shari Sakurai, author

My name is Rhiannon D'Averc, and I'm an author and ghostwriter based in the UK. To date, I've had over 100 books published. I live in Kent with my husband and son and also keep myself busy as the Editor in Chief of London Runway, an indie fashion magazine.

Serial Investigations follows a pair of private detectives, best friends and sharp minds harbouring a dark secret that is slowly destroying each of them from the inside. It's an extreme slow-burn romance with serial killings, references to real crimes, and the city of London as a central location.

    Review to come. Another amazing story that had me biting my nails hard and I'm not a nail biter. So so good

    I enjoyed the case in this story. With that, we also get to experience Will and his parents together. This all helps make for another good story.

    I received an ARC and this is my unbiased opinion

    5.0 out of 5 stars The mystery is just as intriguing as ever
    Reviewed in the United Kingdom on December 29, 2021
    When Will and Ram learn that Alex has a locked room case, Ram is determined to get involved. After all what PI could resist a challenge like this? However, both Alex and the new DI aren’t too keen on having their input, not that this will stop Ram from trying! But first they need to survive a visit to Will’s parents who have no idea that their son is gay, and that Ram is anything more than a friend. Events threaten to push them apart as does Will’s father when he finally learns the truth. Throwing themselves into the case might be what they both need, especially when it seems that the police may need their help after all.

    I couldn’t wait to read book 7 in the series. I have loved Will and Ram since book 1 and the series just keeps getting better and better. Now that they are in a relationship, they have further difficulties to overcome. Despite some old issues threatening to come between them, what I love about this couple is that they are there for each other when it counts despite everything that is thrown at them.

    The mystery is just as intriguing as ever and I enjoyed following the case and trying to work it out for myself too! Again it was full of suspense and twists that I never saw coming!

    I thoroughly enjoyed Blood Pressure and cannot wait to read book 8 in the series!

    Reviewed in the United Kingdom on April 24, 2021
    Well the gorgeous Ram is back again with his baby by his side. There is a mystery to solve and Ram is on his own this time as Will tries to please his family. Both the boys struggle with their problems and each rely on the other for support. I am not sure this will ever be an angst free relationship but it is getting better. A good read, but start at book one.
