Contemporary English-language mystery fiction increasingly places women at the centre of investigations, not merely as victims whose suffering motivates a male detective. This article examines how gendered power and the politics of hidden knowledge shape four novels: Gillian Flynn’s Gone Girl (2012), Paula Hawkins’s The Girl on the Train (2015), Sujata Massey’s The Widows of Malabar Hill (2018), and Oyinkan Braithwaite’s My Sister, the Serial Killer (2018). Drawing on feminist literary criticism, intersectionality, and theories of gender performance, the study uses comparative close reading of characterization, narration, institutional authority, domestic space, and disclosure.

In this study, we model an SEIR model, which is an epidemic model. We study the existence of the solution of the model. Also, we study the positive variance of the model. Again, we will find the Basic reproduction number (R_0) which is very important for any disease to know its characteristics (endemic, epidemic and pandemic). We also discuss the disease free-equilibrium (DFE) point and its stability analysis by using Routh - Hurwitz stability criterion.

India and the Gulf Cooperation Council (GCC) maintain one of India’s most significant trade partnerships. Bilateral merchandise trade reached approximately USD 178.56 billion in FY 2024-25 and remained near USD 178.66 billion in FY 2025-26, accounting for about 15 per cent of India’s global trade. Indian exports stood at roughly USD 56.87 billion while imports were USD 121.66–121.68 billion, producing a structural deficit driven overwhelmingly by crude oil, liquefied natural gas and related products. This paper analyses the patterns of trade, evaluates opportunities arising from the India–UAE CEPA (in force 2022), the India–Oman CEPA (in force 2026) and the formal launch of full GCC Free Trade Agreement negotiations in February 2026, and examines challenges including the persistent trade imbalance, energy dependence, non-tariff barriers and geopolitical risks.
