Book Review: The Mystery of Number 7

 Book Review: The Mystery of Number 7

Author: Dr. A.G. Malavika

Publisher: Akshara Publications (2026)

Genre: Mystery / Crime Thriller / Medical Suspense 


Executive Summary

In her latest installment, Dr. A.G. Malavika—an ophthalmologist by profession and award-winning author—delivers an engaging procedural mystery centered around the high-pressure world of postgraduate medical residency. The novel follows 22-year-old twin detectives, Jinu and Jamie Varghese (famously dubbed the "J Girls"), as they step into a complex web of tragedy, dark patterns, and cover-ups stretching across several medical institutions. 


Plot Overview

The story kicks off when the "J Girls" receive an urgent call regarding the tragic death of Dr. Akhila, a bright second-year Ophthalmology resident found dead in her vehicle under suspicious circumstances. While initial appearances suggest suicide fueled by intense departmental harassment, subtle clues—including a mysterious green-ink inscription ("777") and a distinct symbol—indicate something far more deliberate.  

As the twin detectives collaborate with law enforcement across Kerala and Tamil Nadu, they discover a chilling pattern of similar cases. The trail leads them through high-stakes academic environments, eerie threats, local cultural festivals, financial anomalies, and shadowy figures exploiting vulnerable students. The sisters must race against time and decipher the cryptic significance of the number 7 before another victim falls. 



Key Themes & Strengths

1. Insider Perspective on Medical Culture

Drawing directly from her medical background, Dr. Malavika brings an authentic grit to the setting. The story touches on real-world issues within medical residency—mental health struggles, extreme academic pressures, and systemic toxicity—giving the investigative backdrop an impactful, grounded reality.


2. Rich Regional Setting & Local Flavor

The novel excels at transporting the reader across South India. From the bustling aisles of LuLu Hypermarket in Kochi to the solemn halls of Tirunelveli and Thiruvananthapuram, the story is infused with rich local culture. Readers are treated to vivid descriptions of local landmarks, temple festivals (Thiruvizha), historical sites in Fort Kochi, and regional delicacies, making the backdrop feel alive.


3. Pacing & Pattern-Based Puzzle

The core investigation relies heavily on pattern recognition—cryptic symbols, numerical codes, and timeline connections. The author keeps the momentum swift, moving fluidly between crime scenes, forensic breakthroughs, and suspenseful confrontations without revealing the mastermind prematurely. 


Final Verdict

The Mystery of Number 7 is a fast-paced, atmospheric whodunit that successfully blends crime-procedural tropes with poignant social commentary on medical education. Fans of light amateur-sleuth detective fiction and regional thrillers will appreciate the dynamic between the J Girls and the clever, puzzle-box structure of the plot.


Rating: ⭐⭐⭐⭐☆ (4/5)

Recommended For: Readers who enjoy medical thrillers, twin-detective dynamics, and procedural mysteries set against rich cultural backdrops.

Is studying abroad a boon or a bane?

We have always had a debate when it comes to the topic - "Is studying abroad a boon or a bane?" The ideas differ from person to person. If you ask me, I would surely say that Studying Abroad is certainly a boon. Why is that? India is home to many universities which are known worldwide. Having said that, we must also accept the fact that none of them are in Top 20 at least. While there are many factors that attributes to this, when a person has the means to afford it combined with interest and talent, I do not see the reason as to why one shouldn't be educated abroad? While few study for their status symbol, majority of them predominantly study abroad to enhance their career. There is no doubt in it.
