“she found herself staring into his mesmeric gaze”

I found it:

While reading The Beetle by Richard Marsh when he says,

“I was far, yet, from being my own man; I realised that he exercised on me a degree of mesmeric force which I had never dreamed that one creature could exercise on another; but, at least, I was no longer in doubt as to whether I was or was not dead. I knew I was alive.” (28)
