My suggestion is, if you want to sound him out, come to F'bleau, put yourself up at a charming hostelry called the Hotel de L'Aigle Noir for a couple of days, contact Trevanny by ringing his shop, make an appointment and talk it over.
Hauxe proposatzen dizut: neurria hartu nahi badiozu, etorri F'bleaura, pasa egun pare bat L'Aigle Noir hotel xarmangarrian, kontaktatu Trevannyrekin bere dendara telefonoz deituta, zita bat izendatu eta azaldu zure asmoa.
