Case Study: Cheating in Berlin Proven

My husband cheats: Proof of visits to a brothel

A desperate wife needed the help of private detectives in Berlin. She believed that her husband had a mistress and would also give money to her.

This suspicion arose as the couple became increasingly divided in the recent past. The husband repeatedly spent money on business trips without being able to explain the whereabouts. His behaviour towards women had massively changed negatively.

He has also been on business trips to Berlin from time to time. He could not give clear answers to questions about his whereabouts and exactly what he did there in the evening. The woman did not want to give up her long-standing marriage so easily. That is why she entrusted the A Plus Detective Agency with checking her husband. So she wanted to know more about his whereabouts. She wanted to be sure of a possible lover.

First, an attempt was made to find a suitable day for a check up in a conversation with the customer. That was quite easy, as the husband was always unavailable from the afternoon. On such a day, the observation should take place with two investigators. They should check what he is doing and whether he is seeing another woman.

Personal observation in Berlin

Already at 10.00 o’clock the observation was taken at the Berlin hotel of the man. In the course of the day, the husband left the house. He got into a rental car and drove to business appointments.

After the business appointments he drove to Kurfürstendamm. There he looked at the jewellery display. He then entered the shop and was approached by a saleswoman. But he didn’t buy any jewellery there.

Then he went to a perfumery and left with a small bag. Then he ate something at a restaurant.

He got out and went to a brothel. On his way there he put on a hood, apparently not to be recognized. One of the investigators could only follow with a delay. Inside the brothel he could no longer determine the exact whereabouts of the unfaithful husband. However, the man was not in the visible area. After about an hour the unfaithful man came out of the room of one of the prostitutes. At the customer’s request, the private detectives ended the mission on site.

With this result the wife finally got certainty about her husband. The successful deployment of private detectives in Berlin had brought light into the darkness. So it explained where the money was.

Is your husband often on business trips in Berlin? Then we will clarify for you whether he cheats on you or not.

People Search in Berlin

We often receive inquiries from customers from all over the world who are looking for the current address of a person from Berlin. These could be, for example:

  • Old friends
  • Fellow students
  • Debtor
  • Business partner
  • Family member and relatives
  • Heirs

Of all these people, our private detectives can find a new address for you. We investigate very discreetly and determine the location if necessary.

In justified cases, a background check can also check whether the person is married, has children, who the employer is, whether they have high debts and much more information.

Berlin Private Detective – the costs

Whoever contacts a detective agency would obviously like to know in advance what costs he has to calculate for an order. This question is justifiable and understandable. But it is not easy to answer, because the prices for the services are only case-related.

Each case is different from others and therefore the prices are different. In order to give you clear information about the costs of a private detective investigation in Berlin, we need case-related information. Our knowledge of the facts puts us in a position to make you a fair offer.

The costs of an observation are in a different category than determining the new address of a debtor who has relocated. And the prices for the sweep for listening devices (TSCM) are different from those for the examination of fingerprints. Each different form of service has its own price category, so advance telephone consultation is indispensable for price calculation.

Let us advise you now without obligation. Write us a message or simply give us a call. You can reach our English-speaking staff from 9 am to 5 pm CET (Monday to Friday).
