A City IT consultant and former Bank of England adviser was today under police guard in hospital as detectives waited to question him over the killing of his wife.

Stuart Andrews, 54, was detained in London on Friday over the death of his wife Caroline, 52, the previous day at the rented £500,000 bungalow in Benenden, Kent.

The father-of-four was thought to be suffering from money troubles and the stress of a nightmare commute into the City.

He was also said to be under pressure from his primary school teacher wife’s frail father staying at the family home.

Mr Andrews is also understood to have become increasingly stressed by his inability to secure a mortgage to buy the £550,000 bungalow his family rented.

They were reportedly facing eviction within a fortnight and the couple was said to have rowed over whether to leave the picturesque village, with Mr Andrews wanting to move closer to London to shorten his commute.

The Oxford classics graduate was also thought to have become exhausted by his lengthy commute into the City of London, often leaving home at 5am and returning at 7pm or later.

Their landlord, Charles Lenox-Conyngham, 81, said he was keen to sell them his property, but they never “managed to close the deal.”

He said: “We agreed a price for it this time last year and then Stuart was going to get a mortgage. By the autumn it was painfully clear that it wasn’t going to happen.

“The elderly father caused a problem. Stuart desperately wanted to get a mortgage but Caroline’s father brought an extra cost with carers visiting the home regularly.”

“Stuart had quite a hard life. He would travel up and down to London every day, leaving at 5am and sometimes not getting back until midnight.

“He had a very stressful life with little sleep and they were having to move.”

The couple had been married for 31 years and had four children: Charles, 26, an organist; Henry, 23, a graduate; Polly, 19, a student; and a 14-year-old daughter, the only child to still live with them.

According to his online CV, Mr Andrews was an information management consultant for global business advisers Alix Partners, and had previously worked in IT for banks including HSBC and the Royal Bank of Scotland. He had also worked for three years as an adviser on a IT project for the Bank of England.

During the hunt for Mr Andrews on Friday 30 officers carrying guns piled on to a busy commuter train at Gillingham station and searched it for 90 minutes.

Police have not revealed the nature of Mr Andrews’ injuries or how he had received them.

A Kent Police spokesman said: “He has non-life threatening injuries in hospital. Officers are waiting to speak to him.”
