An interesting extract from A Estrela de Madeleine by Paulo Pereira Cristovao, a book which almost mirrored PJ investigation but used fictional names for the PJ officers involved. This does make you wonder who PJ were targeting in Mar/Apr 2008.

*snipped*
Francisco was talking about the final redaction of the rogatory letters that were to be sent to the British authorities, and which included the request for several diligences. The letters are a poisoned gift, and despite the fact that they target several people,
there are two persons who are of special interest to the policemen. And those are not the McCanns.It’s a bit like those routine police actions, when you go to a hotel to find out whether a certain individual is staying there, and you ask the receptionist for the guest book. You write down seven names at hazard, and an eighth name, which is the one that actually matters. The receptionist is watching, and although he gave the policeman all the information that was needed, he ended up knowing nothing about the person who was actually the target of that action.
The aforementioned police cunning is revealed in these details. The police has established the logical chain of events a long time ago, and has also understood, for quite some time, that they will hardly find the queen evidence. The process will have to live from details. From the circumstances and the detection of small failures from the person that committed the crime, that concealed it, and logically, has lied.
