I need to check if there's any known Malayalam novel with that title. Let me recall. Kambikatha could be a novel by B. S. Vijah, or another author. Alternatively, it might be a mix-up with "Kandukadha Kambikatha", which is a well-known novel by S. L. Bhyrappa, but that's in Kannada, so maybe a translation? There's a Malayalam translation of "Kandukadha Kambikatha" which I'm not sure if it's been updated.
