Dear Mr. Darren,
Thank you for your letter of 08 April concerning Mr. James.
Mr. James is a competent linguist and for the past 8 years has been employed as senior assistant in our foreign correspondence section. He has always been conscientious and hard-working. Whether he would be capable of taking full responsibility for a large and busy department is difficult to say; his work with us has always been carried out under supervision.
Should you require any further information please do not hesitate to contact me.
