Doctor Ravi Kapoor is tearing his hair out. His ghastly, bottom-pinching father-in-law, Norman, has been thrown out of yet another nursing home and is now cluttering up Ravi's house in Dulwich with fag ends and porn magazines. How can Ravi rid himself of this farting incubus? The good doctor is not alone in his suffering. A generation of fortysomethings is saddled with decrepit parents, each one a shuffling guilt-trip. Costly, clinging, embarrassingly old-fashioned - the old can't die soon enough these days.
Ravi's wheeler-dealer cousin Sonny has a brainwave: what country respects its aged rather than treating them like dirt? India! What country has a peculiar empathy for British charm and 50s decor? India! What country is cheap enough not to drain an inheritance which would otherwise enrich an old person's deserving children? India!
The bravest of Britain's most unwanted are soon being bundled on to eastbound planes. At the front of the queue is Norman, followed by Evelyn, who "doesn't want to be a burden", Jean and her despairing husband, Douglas. New friends and new philosophies await them, not to mention a dramatic change of climate.
Moggach is too fond of colour and comedy for social realism, but neither does she dabble in faux spirituality, and so the India of These Foolish Things is not the country that Ravi accuses his wife of falsely romanticising - "You British go there - oh the poverty, oh the sunsets! ... You all come back with your bazaar bargains, mouthing a lot of mystic tosh."
Nobody could accuse Moggach of mystic tosh. The India she invokes is messy, modern, entrepreneurial; a land of sharp suits and legless beggars, a turbulent melting pot where to be old or even a trifle deaf is not considered to be remotely troublesome, let alone a crime punishable by permanent isolation. Some of the staff are considerably more aged and decrepit than the residents.
Norman, dirty old fossil that he is, has a rather unfortunate fate in store, but the more courageous of our travellers will be handsomely rewarded. They, who imagined their lives were over, will be reborn. The disrespected will have their pride restored, the abandoned will be rescued, the unloved will find true love at last. And Evelyn's New Age daughter will discover that a good shag beats hugging a guru any day.
Moggach, a prolific novelist, makes it her priority to deliver thoughtful, satisfying stories leavened with wit and humanity, peopled by ordinary characters and packaged in excellent unpretentious prose. One often hears the term "a writer's writer". Moggach is one of that much more welcome breed - "a reader's writer".
