We have successfully helped thousands of people from many countries worldwide from infidelity cases through to corporate fraud, whatever the case all are treated with the same professional integrity that they deserve.

When looking for answers we have a variety of methods to achieve the goal, it may not always be the answers you would like as every case is different as no two persons are the same. circumstances can be similar which with our experience helps conclude an investigation in the quickest most cost effective way possible.

We use surveillance, along with undercover work and privileged data sometimes a mixture of all three. Technology in the last few years has helped when using trackers and obtaining real time information. We will review the information you can supply and offer what we feel is the route needed to obtain the answers you seek. You can take our advice or instruct us in whatever way you feel is the direction you would like the investigation to go
