Suspect your husband is cheating on you?
Chances are, you might find him at two spas in the Dhoby Ghaut area, private investigators (PIs) tell The New Paper on Sunday.
Among the litany of spas that offer illegal sexual services in Singapore, the PIs claim that these two massage parlours are the most notorious of the lot.
This is primarily because of the number of cheating cases that have led PIs to them, say the two investigators.
Also, one of the spas is supposedly the largest "dirty" massage establishment in Singapore, says veteran PI James Loh from International Investigators.
"Others might have five to 10 girls. This one is very well run and has 20-plus girls, so there are more options for the customer," says Mr Loh, who has visited both places four times each for separate investigations.
"It is almost like a brothel."
Another PI, who wanted to be known only as Mr Tan, agrees.
He says the two spas have run these services "for quite a number of years", and have so far avoided closure.
Says Mr Tan: "They are well known among regulars. For some reason, I have found myself tracking different cheating spouses to these two places more than once.
"There are also other spas there which are shady, not just these two. Dhoby Ghaut has become like a discreet red light district for richer people, it seems."
Mr Tan reckons that out of every 10 divorce cases he handles, one can be traced to the husband visiting one of the two spas.
What you will see as you enter one of the massage parlours.
The spas are located a block away from each other - one is in Sophia Road and the other is in Prinsep Street. Both opened in 2012.
It is illegal for massage parlour operators to conduct such activities in their establishments.
TNPS is not naming both spas so as not to add to their reputation but has forwarded their names to the authorities.
Last week, seven massage parlour operators were charged in court with running a massage establishment without a valid licence.
Some of these massage parlours are believed to have allowed sexual acts within their premises.
TNPS went undercover to these massage parlours over the past two weeks to find out for sure if they offer sex for money.
Despite posing as first-time customers, we were escorted to partitioned rooms where customers could be alone with the female masseuses.
In one spa, there were as many as 20 such rooms.
The session begins like a regular massage treatment, although the term "massage" is used loosely.
The masseuse, who is dressed in a spa uniform, spends the first hour weakly prodding and rubbing the client's back, while spending a disproportionate amount of time on the thigh area.
It also seems that the masseuse, who says she is from China, makes special effort to repeatedly brush her long hair against the client's face.
Halfway into the hour-long massage is when things take a sleazy turn.
"Would you like other services?" she coos in heavily accented Mandarin.
What other services?
She hems and haws, before flirtatiously asking: "Do you like me?"
Probe further, and she quotes between $50 and $80 for sexual services. But flirtatiousness quickly turns to anger once the extra services are declined.

"You came all the way here, you surely must know what this kind of place is," she sneers as the massage session ends.
Mr Gilbert de Silva, a PI from SecureGuard, says most, if not all, of the women who offer sexual services under the guise of masseuses are foreign nationals, some on tourist visas.
"One of the girls we investigated was a holder of a student permit who attended one of those fly-by-night schools here," he adds.
It is illegal for those on tourist visas and student passes to seek employment in Singapore.
Mr de Silva adds that the men who frequent these massage parlours come from all walks of life, from lawyers to school teachers.
The former police officer has had his men follow his clients' cheating husbands into these spas, not only to document their behaviour, but also to find out more about the woman per their clients' requests.
He says: "Sometimes, our clients want us to gather enough information about these girls and the spas, so they can refer them to the police and get these places in trouble.
"We know quite a lot about some of these girls. Just by acting flamboyant and rich, they give up their phone numbers (to us) easily."
Mr Loh adds that sometimes, the relationship goes beyond a sensual massage with a "happy ending".
Some husbands end up in extramarital affairs with the masseuses, such as in one of his cases last year.
"The wife suspected her spouse was cheating on her, and we found out that the mistress worked in the Prinsep Street massage parlour," he says.
Owners of the two massage parlours could not be reached for comment.
