Half-brother Arthos R competed successfully at 1.60 meters.

Partner in Crime Z is a gelding foaled in 2022, by Pegase van 't Ruytershof out of a Mermus R damsire. A handsome dark bay gelding that is well put together, shows himself off very well and pushes off well, genuine jumping blood that draws in nicely. He moves well, uses his hindquarters well, has a ground-covering canter and jumps with good technique, good front-leg and hind-leg technique, plenty of push off the ground and gets off the floor quickly, very careful and with plenty of scope. The more you see, the more enthusiastic you become. Sharp in a good way, with a good attitude. We are enthusiastic and have a very good impression, certainly a winner. Suitable from amateur to professional.

Sire Pegase van 't Ruytershof jumped very well himself at 1.55m under Jeroen de Winter, but it is above all his offspring that already make him a unique sire. He breeds blood, attitude and particularly attractive, rideable models; it is no coincidence that many of his progeny have ultimately sold as auction toppers. Pegase is a son of Comme il Faut (1.60m) out of a Cornet Obolensky dam and comes from a unique damline, from which the Grand Prix stallion Jilbert van 't Ruytershof also descends.

Damsire Mermus R jumped 1.30m and is an approved KWPN jumping stallion (son of Burggraaf), valued as a damsire.

The dam S.Adermie 2 comes from the renowned Adermie damline and has already produced plenty of sport, half-brothers and half-sisters of Partner in Crime:

Further back in the damline among others Gadermie (1.60m)

La Belle de Jour (1.50m). A strongly bred gelding from a genuine performance damline.
