SYMPATHY FOR CO-WORKER’S DEATH

Dear Felix

I have just heard of your [husband / wife / brother / sister etc.]’ s death. It would be impossible for me to put to words the sincere sympathy I wish to express. I have worked closely with [NAME, ex. Bill] for the past [DURATION, ex. two years] at the office. [His / Her] passing represents the loss of not only a co-worker, but also a very close friend.

If there is anything I can do for you at this difficult time, please let me know.

Regards
Lydia
